	INTERIM REPORTING:
	The interim condensed consolidated financial statements presented herein as of June 30, 2014, and for the three and six month periods ended June 30, 2014 and 2013, are unaudited, but in the opinion of management, include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of financial position, results of operations and cash flows for the periods presented.
	The results of operations for the three and six month periods ended June 30, 2014 do not necessarily indicate the results to be expected for the full year. The December 31, 2013 consolidated balance sheet data was derived from audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. These unaudited interim condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto, contained in our Annual Report on Form 10-K for the year ended December 31, 2013.

Acquisition	'
	ACQUISITION:
	On March 14, 2014 we acquired substantially all of the assets of Laser Design, Inc. (LDI), a privately held company based in Minneapolis, Minnesota for aggregate consideration of $2,633,000 in cash plus the assumption of certain current liabilities of $1,073,000. We also paid aggregate signing bonuses of $475,000 to key executives of LDI which have been accounted for as acquisition consideration. With annual revenues of approximately $6,000,000, LDI provides scanning systems and services to the global 3D scanner and services metrology market and enables us to enter the growing market for general purpose 3D metrology. We also intend to leverage our proprietary 3D sensor technology in LDI’s products to enable differentiated offerings.
	Under the acquisition method of accounting, the total purchase price is allocated to the net tangible and intangible assets acquired, based upon their estimated fair values as of March 14, 2014. During the three months ended June 30, 2014, we completed our valuation work and management review of the assets acquired and liabilities assumed and finalized the purchase price adjustment for the net working capital acquired. Adjustments to provisional amounts reflected in our preliminary purchase price allocation as of March 31, 2014 included a $24,000 decrease in intangible assets and a $46,000 increase in goodwill, among other adjustments. These measurement period adjustments require the revision of comparative financial information for the quarter ended March 31, 2014. The adjustment to intangible assets decreased amortization expense in the three months ended March 31, 2014 by less than $300. None of the other adjustments to the provisional amounts had any impact on our results of operations for the first quarter of 2014.
	The purchase price allocation for our acquisition of LDI is as follows:
	(In thousands)
	Accounts receivable		$	662
	Inventories		551
	Equipment and leasehold improvements		1,507
	Other assets		91
	Intangible assets		573
	Identifiable assets acquired		3,384
	Accounts payable		640
	Accrued expenses and advance customer payments		433
	Liabilities assumed		1,073
	Net identifiable assets acquired		2,311
	Goodwill		797
	Purchase price		$	3,108
	The allocation of the purchase price resulted in recognition of the following identified intangible assets:
		(In thousands)			Weighted Average
					Life-Years
	Software	$	206		7
	Patent	165			7
	Marketing assets and customer relationships	101			9
	Non-compete agreements	101			4
		$	573
	The fair value of the above identified intangible assets was estimated using an income approach. Under the income approach, an intangible asset’s fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. Indications of value are developed by discounting future net cash flows to their present value at market-based rates of return. The software, patent and marketing intangible assets have been appraised using a relief from royalty income methodology; the non-competes using a “with and without” income methodology; and, customer relationships using a multi period excess earnings methodology. The goodwill recognized as a result of the LDI acquisition is primarily attributable to the value of the workforce, as well as unidentifiable intangible assets. We paid a premium over the net tangible and identifiable intangible assets acquired (i.e. goodwill) because owning LDI enables us to have initial access to the general purpose 3D metrology market and allows us to leverage our proprietary 3D sensor technology in LDI’s products.
	All of the goodwill is expected to be deductible for income tax purposes over a 15 year period. The useful life of the intangible assets for income tax amortization purposes was determined based on management’s best estimate of the expected cash flows used to measure the fair value of the intangible assets, adjusted as appropriate for entity-specific factors, including competitive, economic or other factors that may limit the useful life of the intangible assets.
	Since the date of acquisition, LDI contributed approximately $2,200,000 to our revenue in the six months ended June 30, 2014, including approximately $1,700,000 of revenue in the three months ended June 30, 2014. Since the date of acquisition, LDI contributed $224,000 to our net loss in the six months ended June 30, 2014, including $135,000 of net loss in the three months ended June 30, 2014.
	The following unaudited pro forma consolidated financial information presents our revenue and net loss as if the acquisition of LDI occurred on January 1, 2013. The unaudited pro forma consolidated financial information has been prepared for illustrative purposes only and does not purport to be indicative of the results that would have been achieved had the acquisition occurred on January 1, 2013, or of future results. The unaudited pro forma consolidated financial information does not reflect any operating efficiencies and cost savings that may be realized from integration of LDI.

	We incurred approximately $117,000 in LDI related acquisition costs. Approximately $47,000 of these costs are recorded as selling, general and administrative expenses in the first quarter of 2014, with the remaining balance recorded as selling, general and administrative expense in the third and fourth quarters of 2013. The pro forma consolidated net loss for 2014 reflected in the table above was adjusted to exclude all acquisition related costs and the impact of the fair value adjustment to acquisition date inventories of $222,000. The pro forma net loss for 2013 has been adjusted to reflect these items as if the acquisition occurred on January 1, 2013.

Derivative Instruments and Hedges, Assets [Abstract]	'
Derivatives	'
	DERIVATIVES:
	We enter into foreign exchange forward contracts to hedge against the effect of exchange rate fluctuations on cash flows denominated in foreign currencies associated with our subsidiary in Singapore. These transactions are designated as cash flow hedges and are recorded in the accompanying balance sheet at fair value. The effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. Hedge ineffectiveness and the amounts excluded from effectiveness testing recognized in earnings on cash flow hedges were not material for the three and six month periods ended June 30, 2014 and June 30, 2013.
	The maximum length of time over which we hedge our exposure to the variability in future cash flows is 12 months. Accordingly, at June 30, 2014 and June 30, 2013, all of our open foreign exchange forward contracts had maturities of one year or less. The dollar equivalent gross notional amount of our foreign exchange forward contracts designated as cash flow hedges was approximately $7.0 million at June 30, 2014 and $5.7 million at June 30, 2013.
	Reclassifications of amounts from accumulated other comprehensive loss into earnings include accumulated gains (losses) at the time earnings are impacted by the forecasted transaction. The location in the consolidated statements of operations and consolidated statements of comprehensive loss and amounts of gains and losses related to derivative instruments designated as cash flow hedges are as follows:

	Amounts recorded in accumulated other comprehensive loss for the after tax net unrealized loss associated with cash flow hedging instruments was $13,000 at June 30, 2014 and $116,000 at December 31, 2013. We expect to reclassify the June 30, 2014 pretax unrealized gain of $44,000 recorded in accumulated other comprehensive loss to earnings over the next 12 months with the impact offset by cash flows from underlying hedged items. The fair value of our foreign exchange forward contracts representing a gain in the amount of $41,000 at June 30, 2014 has been recorded in other current assets. The fair value of our foreign exchange forward contracts representing a loss in the amount of $58,000 at December 31, 2013 has been recorded in accrued expenses.
	Additional information with respect to the impact of derivative instruments on other comprehensive income (loss) is included in Note 13. Additional information with respect to the fair value of derivative instruments is included in Note 5.
	Our foreign exchange forward contracts contain credit risk to the extent that our bank counter-parties may be unable to meet the terms of the agreements. We minimize such risk by limiting our counter-parties to major financial institutions. We do not expect material losses as a result of defaults by other parties.

Fair Value Measurements	'
	FAIR VALUE MEASUREMENTS:
	We determine the fair value of our assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. We use a fair value hierarchy with three levels of inputs, of which the first two are considered observable and the last unobservable, to measure fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1). The next highest priority is based on quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in non-active markets or other observable inputs (Level 2). The lowest priority is given to unobservable inputs (Level 3). The following provides information regarding fair value measurements for our marketable securities and foreign exchange forward contracts as of June 30, 2014 and December 31, 2013 according to the three-level fair value hierarchy:

	During the six months ended June 30, 2014 and the year ended December 31, 2013 there was no transfers within the three level hierarchy. A significant transfer is recognized when the inputs used to value a security have been changed which merit a transfer between the disclosed levels of the valuation hierarchy.
	The fair value for our U.S. government and agency obligations, corporate debt securities and certificates of deposit and asset backed securities are determined based on valuations provided by external investment managers who obtain them from a variety of industry standard data providers. The fair value for our equity security is based on a quoted market price obtained from an active market.
	The fair value for our foreign exchange forward contracts is based on foreign currency spot and forward rates obtained from reputable financial institutions with resulting valuations periodically validated by obtaining foreign currency spot rate and forward quotes from other industry standard sources, third party or counterparty quotes. The fair value of our foreign exchange forward contracts representing a gain in the amount of $41,000 as of June 30, 2014 has been recorded in other current assets. The fair value of our foreign exchange forward contracts representing a loss in the amount of $58,000 as of December 31, 2013 has been recorded in accrued expenses.
	The carrying amounts of financial instruments such as cash equivalents, accounts receivable, income tax refunds receivable, other assets, accounts payable, and all current liabilities approximate their related fair values due to the short-term maturities of these instruments. Non-financial assets such as equipment and leasehold improvements, goodwill and intangible assets are subject to non-recurring fair value measurements if they are deemed impaired. We had no re-measurements of non-financial assets to fair value during the six months ended June 30, 2014 or June 30, 2013.

Accounting For Stock-Based Compensation	6 Months Ended

Share-based Compensation [Abstract]	'
Accounting For Stock-Based Compensation	'
	ACCOUNTING FOR STOCK-BASED COMPENSATION:
	All equity-based payments to employees, including grants of employee stock options and restricted stock units, are recognized as an expense in our consolidated statement of operations based on the grant date fair value of the award. We utilize the straight-line method of expense recognition over the award’s service period for our graded vesting options. The fair value of stock options granted has been determined using the Black-Scholes model. The compensation expense recognized for all equity based awards is net of estimated forfeitures, which are based on historical data. We have classified equity based compensation within our statement of operations in the same manner as our cash based employee compensation costs.
	Equity based compensation expense in the three months ended June 30, 2014 totaled $153,000 and includes $80,000 for stock option awards, $10,000 for our employee stock purchase plan, $31,000 for unvested restricted stock units and $32,000 for shares issued to our non-employee directors upon their re-election to our board in May 2014. Equity based compensation expense in the six months ended June 30, 2014 totaled $261,000 and includes $150,000 for stock option awards, $18,000 for our employee stock purchase plan, $61,000 for unvested restricted stock units and $32,000 for shares issued to our non-employee directors.
	Equity based compensation expense in the three months ended June 30, 2013 totaled $130,000 and includes $64,000 for stock option awards, $12,000 for our employee stock purchase plan, $24,000 for unvested restricted stock units and $30,000 for shares issued to our non-employee directors upon their re-election to our board in May 2013. Equity based compensation in the six months ended June 30, 2013 totaled $233,000 and includes $130,000 for stock option awards, $24,000 for our employee stock purchase plan, $49,000 for unvested restricted stock units and $30,000 for shares issued to our non-employee directors.
	At June 30, 2014 the total unrecognized compensation cost related to non-vested equity based compensation arrangements was $1,156,000 and the related weighted average period over which it is expected to be recognized is 2.67 years.
	For stock options granted during the six months ending June 30, 2014, we utilized the fair value of our common stock on the date of grant and employed the following key assumptions in computing fair value using the Black-Scholes option-pricing model:
		2014
	Risk-free interest rates	1.55% - 1.65%
	Expected life in years	5.30 - 5.48
	Expected volatility	46.57% - 46.90%
	Dividend yield	—%
	Weighted average fair value on grant date	$3.39
	Stock Options
	We have two stock incentive plans that are administered under the supervision of the Compensation Committee of the Board of Directors. As of June 30, 2014, there are 940,166 shares of common stock reserved in the aggregate for issuance of options and other stock based benefits under these plans, including restricted stock units and share grants to employees, officers and others. Reserved shares underlying canceled options are available for future grant under our active plan. Options are granted at an option price per share equal to or greater than the market value of our common stock on the date of grant. Generally, options granted to employees vest over a four-year period and expire seven years after the date of grant. The plans allow for option holders to tender shares of our common stock as consideration for the option price, provided that the tendered shares have been held by the option holder at least six months. As of June 30, 2014, there were 286,472 shares of common stock available under our active plan for future issuance to employees, officers and others.
	The following is a summary of stock option activity for the six months ended June 30, 2014:
		Options Outstanding			Weighted Average Exercise
					Price Per Share
	Outstanding, December 31, 2013	586,483			$	8.07
	Granted	170,000			7.73
	Exercised	(59,200	)		5.04
	Expired	(43,851	)		14.8
	Forfeited	(52,498	)		7.5
	Outstanding, June 30, 2014	600,934			$	7.83
	Exercisable, June 30, 2014	273,354			$	8.73
	The intrinsic value of an option is the amount by which the fair value of the underlying stock exceeds its exercise price. At June 30, 2014, the weighted average remaining contractual term of all outstanding options was 4.42 years and their aggregate intrinsic value was $546,580. At June 30, 2014, the weighted average remaining contractual term of options that were exercisable was 2.28 years and their aggregate intrinsic value was $228,082. We received proceeds of $298,358 from the exercise of stock options in the six months ended June 30, 2014. We received no proceeds from the exercise of stock options in the six months ended June 30, 2013.
	Restricted Stock Units
	Our 1998 Stock Incentive Plan also permits our Compensation Committee to grant other stock-based benefits, including restricted stock units. Restricted stock units are valued at a price equal to the fair market value of our common stock on the date of grant, vest over a four year period provided the employee is still working for the company and entitle the holders to one share of our common stock for each restricted stock unit. The aggregate fair value of outstanding restricted stock units based on the closing share price of our common stock on June 30, 2014 was $422,000. The aggregate fair value of restricted stock units that vested in the six months ended June 30, 2014, based on the closing share price of our common stock on the vesting date, was $34,796.
	A summary of activity in non-vested restricted stock units for the six months ended June 30, 2014 is as follows:
	Non-vested restricted stock units		Shares			Weighted Average Grant Date
						Fair Value
	Non-vested at December 31, 2013		46,943			$	6.82
	Granted		20,000			6.97
	Vested		(5,433	)		7.31
	Forfeited		(8,750	)		7.5
	Non-vested at June 30, 2014		52,760			$	6.71
	Employee Stock Purchase Plan
	We have an Employee Stock Purchase Plan available to eligible U.S. employees. Under terms of the plan, eligible employees may designate from 1% to 10% of their compensation to be withheld through payroll deductions, up to a maximum of $6,500 in each plan year, for the purchase of common stock at 85% of the lower of the market price on the first or last day of the offering period. There were no shares issued under this plan in the six months ended June 30, 2014 or June 30, 2013. As of June 30, 2014, 153,926 shares remain available for future issuance under this plan.
	Stock Grant Plan for Non-Employee Directors
	Our stock grant plan for non-employee directors provides for automatic grants of 1,000 shares of our common stock to each of our non-employee directors upon their re-election to the Board of Directors. The plan allows for the issuance of up to 60,000 shares of our common stock, including an additional 30,000 shares authorized in May 2014, and will expire on May 19, 2018. We issued a total of 4,000 shares of common stock under this plan in connection with our annual meeting in May 2014, resulting in $32,000 of stock compensation expense in the three and six months ended June 30, 2014. As of June 30, 2014, 32,000 shares of common stock are reserved in the aggregate for future issuance under this plan.

	Warranty costs:
	We provide for the estimated cost of product warranties, which extend for periods from one to three years after purchase, at the time revenue is recognized. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of component suppliers, warranty obligations are affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from our estimates, revisions to the estimated warranty liability would be required and could be material. Our warranty liability is included as a component of accrued expenses. At the end of each reporting period we revise our estimated warranty liability based on these factors.
	A reconciliation of the changes in our estimated warranty liability is as follows:

	Amortization of patents has been classified as research and development expense in the accompanying statements of operations. Estimated aggregate amortization expense based on current intangibles for the next five years is expected to be as follows: $94,000 for the remainder of 2014, $147,000 in 2015, $119,000 in 2016, $94,000 in 2017, $67,000 in 2018 and $62,000 in 2019.
	Intangible and other long lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment loss would be recognized when future undiscounted cash flows expected to result from use of the asset and eventual disposition are less than the carrying amount.

	RESTRUCTURING AND SEVERANCE COSTS:
	Severance costs of $952,000 were incurred in the fourth quarter of 2013 when we reduced our global workforce by approximately 30 employees. Expenses for contract workers were also reduced. The workforce reduction was undertaken to strengthen our commitment to cost control, minimize losses and to improve focus on market support for our products.

Net Loss Per Share	'
	NET LOSS PER SHARE:
	Net loss per basic and diluted share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Common equivalent shares consist of common shares to be issued upon exercise of stock options, restricted stock units and from participation in our employee stock purchase plan, as calculated using the treasury stock method. All potentially dilutive common equivalent shares are excluded from the calculations of net loss per diluted share due to their anti-dilutive effect. As a result, no common equivalent shares were included in the calculations of net loss per diluted share for the three and six month periods ended June 30, 2014 or June 30, 2013. The components of net loss per basic and diluted share are as follows:
	(In thousands except per share amounts)	Net Loss			Weighted Average	Per Share Amount

Reclassifications to earnings related to cash flow hedging instruments are discussed in Note 4. Income taxes are not provided for foreign currency translation adjustments relating to permanent investments in international subsidiaries. We have recorded a valuation allowance against all of our United States and Singapore based deferred tax assets.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	INCOME TAXES:
	We recorded income tax expense of $54,000 in the six months ended June 30, 2014, compared to $74,000 in the six months ended June 30, 2013. Our income tax expense in both the six months ended June 30, 2014 and the six months ended June 30, 2013 reflects minimal state income tax expense and foreign income tax expense associated with our subsidiaries in the United Kingdom and China.
	We currently have significant deferred tax assets as a result of temporary differences between taxable income on our tax returns and U.S. GAAP income, research and development tax credit carry forwards and federal, state and foreign net operating loss carry forwards. A deferred tax asset generally represents future tax benefits to be received when temporary differences previously reported in our financial statements become deductible for income tax purposes, when net operating loss carry forwards are applied against future taxable income, or when tax credit carry forwards are utilized on our tax returns. We assess the realizability of our deferred tax assets and the need for a valuation allowance based on the guidance provided in current financial accounting standards.
	Significant judgment is required in determining the realizability of our deferred tax assets. The assessment of whether valuation allowances are required considers, among other matters, the nature, frequency and severity of any current and cumulative losses, forecasts of future profitability, the duration of statutory carry forward periods, our experience with loss carry forwards not expiring unused and tax planning alternatives.
	We have concluded that a valuation allowance is needed for all of our United States and Singapore based deferred tax assets due to the losses we have sustained since 2011 and our near term financial outlook. In analyzing the need for a valuation allowance, we considered our history of operating results for income tax purposes over the past three years in each of the tax jurisdictions where we operate, statutory carry forward periods and tax planning alternatives. Finally, we considered both our near and long-term financial outlook and timing regarding when we might return to profitability. After considering all available evidence both positive and negative, we concluded that a valuation allowance is needed for all of our U.S. and Singapore based deferred tax assets at June 30, 2014 and December 31, 2013.
	Deferred tax assets at June 30, 2014 include net operating loss carry forwards incurred in the UK by CyberOptics Ltd., which was acquired in 1999. A valuation allowance has not been recorded against these deferred tax assets. The utilization of these net operating loss carry forwards is dependent on CyberOptics Ltd.’s ability to generate sufficient UK taxable income during the carry forward period.

Contingencies	'
	CONTINGENCIES:
	We are periodically a defendant in miscellaneous claims and disputes in the ordinary course of business. While the outcome of these matters cannot be predicted with certainty, management presently believes the disposition of these matters will not have a material effect on our financial position, results of operations or cash flows.
	In the normal course of business to facilitate sales of our products and services, we at times indemnify other parties, including customers, with respect to certain matters. In these instances, we have agreed to hold the other parties harmless against losses arising out of intellectual property infringement or other types of claims. These agreements may limit the time within which an indemnification claim can be made, and almost always limit the amount of the claim. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made, if any, under these agreements have not had a material impact on our operating results, financial position or cash flows.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Recent Accounting Developments	'
	RECENT ACCOUNTING DEVELOPMENTS:
	In May 2014, the Financial Accounting Standards Board (FASB) issued guidance on the recognition of revenue from contracts with customers (ASU No. 2014-09, Revenue from Contracts with Customers). Revenue recognition will depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application. The guidance is effective January 1, 2017 and early adoption is not permitted. The Company is currently evaluating the method of adoption and the impact of the new guidance on the consolidated financial statements.
	In April 2014, the FASB issued guidance that changes the criteria for reporting a discontinued operation (ASU No. 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity). According to the new guidance, only disposals of a component that represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results are a discontinued operation. The new guidance also requires expanded disclosures about discontinued operations and disposals of a significant part of an entity that does not qualify for discontinued operations reporting. The guidance is effective beginning January 1, 2015 with early adoption permitted, but only for disposals (or classifications as held for sale) that have not been reported in previously-issued financial statements. The impact on our consolidated financial statements will be dependent on any transaction that is within the scope of the new guidance.
	In July 2013, the FASB issued guidance regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists (ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists). Under certain circumstances, unrecognized tax benefits should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The guidance was effective January 1, 2014, and was adopted by us in the first quarter. The guidance is a change in financial statement presentation only and had no impact on our consolidated financial results or financial position.
