Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (“Teledyne” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with accounting principles generally accepted in the United States as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 28, 2014 (“ 2014 Form 10-K”). In the opinion of Teledyne’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of September 27, 2015 and the consolidated results of operations and consolidated comprehensive income for the three and nine months then ended and consolidated cash flows for the nine months then ended. The results of operations and cash flows for the period ended September 27, 2015 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current period presentation. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers , which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In July 2015, the FASB deferred the effective date by one year, but will allow early adoption as of the original adoption date. This new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is currently in the process of determining its implementation approach and assessing the impact on the consolidated financial statements and footnote disclosures.

Business Combinations and Investments, Goodwill and Acquired Intangible Assets [Abstract]
Business Combinations and Investments, Goodwill and Acquired Intangible Assets	Business Combinations and Investments, Goodwill and Acquired Intangible Assets On June 5, 2015, Teledyne DALSA BV, a Netherlands-based subsidiary, acquired Industrial Control Machines SA (“ICM”) for an initial payment of $21.4 million , net of cash acquired. An additional $2.6 million of the purchase price is subject to an indemnification holdback, all or a portion of which is payable in December 2016. Based in Liège, Belgium, ICM is a leading supplier of portable X-ray generators for non-destructive testing applications, as well as complete X-ray imaging systems for on-site security screening and is part of the Digital Imaging segment. On April 29, 2015, Teledyne DALSA, Inc. acquired the remaining 49% noncontrolling interest in the parent company of Optech Incorporated (“Optech”) for $22.0 million in cash. As a result of the purchase, the difference between the cash paid and the balance of noncontrolling interest was recorded to additional paid in capital. The balance of the noncontrolling interest of $41.2 million at December 28, 2014 decreased by $0.3 million for the net loss and $1.3 million in translation adjustments prior to the purchase which eliminated the remaining balance. The balance of the noncontrolling interest of $47.0 million at December 29, 2013 decreased by $0.8 million for the net loss and $1.9 million in translation adjustments, resulting in a balance of $44.3 million at September 28, 2014. Teledyne no longer has any noncontrolling interests at September 27, 2015. Optech is part of the Digital Imaging segment. On February 2, 2015, Teledyne acquired Bowtech Products Limited (“Bowtech”) through a U.K.-based subsidiary for $18.8 million in cash, net of cash acquired and including an estimated working capital adjustment. Based in Aberdeen, Scotland, Bowtech designs and manufactures harsh underwater environment vision systems and is part of the Instrumentation segment. Also in 2015, Teledyne made an additional investment in Ocean Aero, Inc. (“Ocean Aero”) and now owns a 36.9% interest in Ocean Aero which is accounted for under the equity method. During 2014, Teledyne made four acquisitions, the largest of which was Bolt Technology Corporation (“Bolt”) in November 2014. All of the 2014 acquisitions are part of the Instrumentation segment. Teledyne funded the purchases from borrowings under its credit facility and cash on hand. The ICM, Bowtech and Optech acquisitions were funded with cash held by foreign subsidiaries. The results of the acquisitions have been included in Teledyne’s results since the dates of the respective acquisition. For a further description of the Company’s acquisition activity for the fiscal year ended December 28, 2014 , please refer to Note 3 of our 2014 Form 10-K. Teledyne’s goodwill was $1,149.5 million at September 27, 2015 and $1,150.6 million at December 28, 2014 . The decrease in the balance of goodwill in 2015 resulted from the impact of exchange rate changes, mostly offset by recent acquisitions. Goodwill resulting from the Bowtech and ICM acquisitions will not be deductible for tax purposes. Teledyne’s net acquired intangible assets were $253.4 million at September 27, 2015 and $277.6 million at December 28, 2014 . The decrease in the balance of acquired intangible assets in 2015 resulted from amortization and the impact of exchange rate changes, partially offset by acquired intangibles for recent acquisitions. The Company is still in the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the ICM, Bowtech and Bolt acquisitions. The Company made preliminary estimates as of September 27, 2015 since there was insufficient time between the acquisition dates and the end of the period to finalize the analysis.

Derivative Instruments

Derivative Instruments	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Teledyne transacts business in various foreign currencies and has international sales and expenses denominated in foreign currencies, subjecting the Company to foreign currency risk. The Company’s primary foreign currency risk management objective is to protect the United States dollar value of future cash flows and minimize the volatility of reported earnings. The Company utilizes foreign currency forward contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in Canadian dollars. These contracts are designated and qualify as cash flow hedges. Cash Flow Hedging Activities The effectiveness of the cash flow hedge contracts, excluding time value, is assessed prospectively and retrospectively on a monthly basis using regression analysis, as well as using other timing and probability criteria. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedges and must be highly effective in offsetting changes to future cash flows on hedged transactions. The effective portion of the cash flow hedge contracts’ gains or losses resulting from changes in the fair value of these hedges is initially reported, net of tax, as a component of AOCI in stockholders’ equity until the underlying hedged item is reflected in our consolidated statements of income, at which time the effective amount in AOCI is reclassified to cost of sales in our consolidated statements of income. Net deferred losses recorded in AOCI, net of tax, for contracts that will mature in the next twelve months total $4.9 million . These losses are expected to be offset by anticipated gains in the value of the forecasted underlying hedged item. In the event that the gains or losses in AOCI are deemed to be ineffective, the ineffective portion of gains or losses resulting from changes in fair value, if any, is reclassified to other income and expense. In the event that the underlying forecasted transactions do not occur, or it becomes remote that they will occur, within the defined hedge period, the gains or losses on the related cash flow hedges will be reclassified from AOCI to other income and expense. During the current reporting period, all forecasted transactions occurred and, therefore, there were no such gains or losses reclassified to other income and expense. As of September 27, 2015 , Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $99.0 million . These foreign currency forward contracts have maturities ranging from December 2015 to February 2018. Non-Designated Hedging Activities In addition, the Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign-currency-denominated monetary assets and liabilities, including intercompany receivables and payables. As of September 27, 2015 , Teledyne had foreign currency contracts of this type in the following pairs (in millions): Contracts to Buy Contracts to Sell Currency Amount Currency Amount Canadian Dollars C$ 50.0 U.S. Dollars US$ 38.0 Euros € 8.1 U.S. Dollars US$ 9.1 Great Britain Pounds £ 0.9 Australian Dollars A$ 1.9 Great Britain Pounds £ 15.5 U.S. Dollars US$ 23.9 Singapore Dollars S$ 1.7 U.S. Dollars US$ 1.2 U.S. Dollars US$ 0.8 Japanese Yen ¥ 100.0 The gains and losses on these derivatives which are not designated as hedging instruments are intended to, at a minimum, partially offset the transaction gains and losses recognized in earnings. All derivatives are recorded on the balance sheet at fair value. As discussed below, the accounting for gains and losses resulting from changes in fair value depends on the use of the derivative and whether it is designated and qualifies for hedge accounting. Teledyne does not use foreign currency forward contracts for speculative or trading purposes. The effect of derivative instruments designated as cash flow hedges in our condensed consolidated financial statements for the third quarter and nine months ended September 27, 2015 and September 28, 2014 was as follows (in millions): Third Quarter Nine Months 2015 2014 2015 2014 Net loss recognized in AOCI (a) $ (4.2 ) $ (3.1 ) $ (8.2 ) $ (2.9 ) Net loss reclassified from AOCI into cost of sales (a) $ (2.4 ) $ (0.6 ) $ (5.6 ) $ (2.4 ) Net foreign exchange (loss) gain recognized in other income and expense (b) $ (0.1 ) $ 0.2 $ 0.2 $ 0.5 a) Effective portion, pre-tax b) Amount excluded from effectiveness testing The effect of derivative instruments not designated as cash flow hedges recognized in other income and expense for the third quarter and nine months ended September 27, 2015 was expense of $4.6 million and $7.1 million , respectively. The effect of derivative instruments not designated as cash flow hedges in other income and expense for the third quarter and nine months ended September 28, 2014 was $3.1 million and $2.0 million of gain, respectively.

Earnings Per Share

Earnings Per Share	9 Months Ended
	Sep. 27, 2015
Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic and diluted earnings per share were computed based on net earnings. The weighted average number of common shares outstanding during the period was used in the calculation of basic earnings per share. This number of shares was increased by contingent shares that could be issued under various compensation plans as well as by the dilutive effect of stock options based on the treasury stock method in the calculation of diluted earnings per share. In October 2011, the Company’s Board of Directors authorized a stock repurchase program to repurchase up to 2,500,000 shares of the Company’s common stock. In September 2014, the Company entered into a $101.6 million accelerated share repurchase (“ASR”) agreement with a financial institution (“ASR Counterparty”) in a privately negotiated transaction for 1,030,000 shares of the Company’s common stock at an initial price of $98.62 per share. Pursuant to the ASR agreement, in September 2014, the Company advanced $101.6 million to the ASR counterparty and received 927,000 shares of common stock, which used $91.4 million of the $101.6 million advanced, representing 90% of the estimated shares to be repurchased under the ASR agreement. In May 2015, the ASR agreement was settled and Teledyne received 78,522 shares of common stock on June 3, 2015. On January 27, 2015, the Company’s Board of Directors authorized an additional stock repurchase program authorizing the Company to repurchase up to an additional 2,500,000 shares of its common stock. On February 2, 2015, the Company entered into a $142.0 million ASR agreement with a financial institution in a privately negotiated transaction for 1,500,000 shares of the Company's common stock at an initial price of $94.68 per share. Pursuant to the ASR agreement, in February 2015, the Company advanced $142.0 million to the ASR counterparty and received 1,425,000 shares of common stock, which used $134.9 million of the $142.0 million advanced, representing 95% of the estimated shares to be repurchased under the ASR agreement. The up-front payments were accounted for as a reduction to stockholders’ equity in the Company’s Condensed Consolidated Balance Sheet in the period the payments were made. The total number of shares of common stock repurchased under each ASR is based on the average of the daily volume-weighted average prices of the common stock during the term of the respective ASR, less a discount. At settlement, the ASR Counterparty may be required to deliver additional shares of the Company’s common stock to the Company or, under certain circumstances, the Company may be required to deliver shares of its common stock or make a cash payment to the ASR Counterparty. Final settlement of the September 2014 ASR agreement occurred in May 2015 as noted above. Final settlement of the February 2015 ASR agreement is expected to occur in December 2015, although the settlement may be accelerated at the ASR Counterparty’s option. The Company has treated the ASRs as a treasury share repurchase of common stock in the period the shares were delivered for purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The ASRs meet all of the applicable criteria for equity classification, and, therefore, is not accounted for as a derivative instrument. The February 2015 ASR was funded by cash on hand and floating rate borrowings of $120.0 million under the $750 million credit facility. The 2011 and 2015 stock repurchase authorizations are expected to remain open continuously, and the number of shares repurchased will depend on a variety of factors, such as share price, levels of cash and borrowing capacity available, alternative investment opportunities available immediately or longer-term, and other regulatory, market or economic conditions. Future repurchases are expected to be funded with cash on hand and borrowings under the company’s credit facility. Teledyne has 2,259,409 shares of treasury stock at September 27, 2015.

Inventory Disclosure [Abstract]
Inventories	Inventories Inventories are stated at the lower of cost or market, less progress payments. Inventories are valued under the FIFO method, LIFO method and average cost method. Inventories at cost determined on the average cost or the FIFO methods were $257.4 million at September 27, 2015 and $241.8 million at December 28, 2014 . The remainder of the inventories using the LIFO method were $104.0 million at September 27, 2015 and $98.1 million at December 28, 2014 . Interim LIFO calculations are based on the Company’s estimates of expected year-end inventory levels and costs since an actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Because these are subject to many factors beyond the Company’s control, interim results are subject to the final year-end LIFO inventory valuation. Inventories consist of the following (in millions): Balance at September 27, 2015 December 28, 2014 Raw materials and supplies $ 150.6 $ 143.1 Work in process 167.9 153.5 Finished goods 42.9 43.3 361.4 339.9 Progress payments (13.5 ) (11.6 ) LIFO reserve (16.4 ) (16.5 ) Total inventories, net $ 331.5 $ 311.8

Some of the Company’s products are subject to specified warranties and the Company provides for the estimated cost of product warranties. The adequacy of the pre-existing warranty liabilities is assessed regularly and the reserve is adjusted as necessary based on a review of historic warranty experience with respect to the applicable business or products, as well as the length and actual terms of the warranties, which are typically one year . The product warranty reserve is included in current and long term accrued liabilities on the balance sheet. Changes in the Company’s product warranty reserve during the first nine months of 2015 and 2014 are as follows (in millions): Nine Months 2015 2014 Balance at beginning of year $ 18.5 $ 17.3 Accruals for product warranties charged to expense 4.6 2.7 Cost of product warranty claims (5.5 ) (4.1 ) Acquisitions 0.2 0.1 Balance at end of period $ 17.8 $ 16.0

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax provision is calculated using an estimated annual effective tax rate, based upon expected annual income, permanent items, statutory rates and planned tax strategies in the various jurisdictions in which the Company operates. However, losses in certain jurisdictions and discrete items, such as the resolution of uncertain tax positions, are treated separately. The Company’s effective income tax rate for the third quarter and first nine months of 2015 was 21.4% and 26.3% respectively. The Company’s effective income tax rate for the third quarter and first nine months of 2014 was 19.2% and 24.6% , respectively. The first nine months of 2015 included $8.5 million in net discrete income tax benefits, compared with net discrete income tax benefits of $8.2 million for the first nine months of 2014. The third quarter of 2015 included net discrete income tax benefits of $7.4 million compared with net discrete income tax benefits of $6.1 million for the third quarter of 2014 . The net discrete income tax benefits in 2015, included the remeasurement of uncertain tax positions due to expiration of statute of limitations, favorable resolution of tax matters, and certain deferred tax adjustments. The net discrete income tax benefits in 2014, included the remeasurement of uncertain tax positions, primarily due to an expiration of statute of limitations and a favorable resolution of a tax matter. Excluding net discrete income tax items in both periods, the effective tax rates would have been 33.5% for the third quarter of 2015 and 30.8% for the first nine months of 2015 and 28.1% for the third quarter of 2014 and 28.5% for the first nine months of 2014. During the next twelve months, it is reasonably possible that expirations of the statutes of limitations could reduce unrecognized tax benefits by $3.6 million . Of the $3.6 million , $3.1 million would affect the effective tax rate.

In August 2015, the Company entered into a note purchase agreement providing for a private placement of $125.0 million in aggregate principal amount of senior unsecured notes expected to be issued on November 5, 2015. The notes will consist of $25.0 million of 2.81% senior unsecured notes due November 5, 2020, and $100.0 million of 3.28% senior unsecured notes due November 5, 2022. Teledyne estimates the fair value of its long-term debt based on debt of similar type, rating and maturity and at comparable interest rates. The Company’s long-term debt is considered a level 2 fair value hierarchy and is valued based on observable market data. The estimated fair value of Teledyne’s long-term debt at September 27, 2015 and December 28, 2014 , approximated the carrying value. At September 27, 2015 , the Company had $9.2 million in capital leases, of which $1.3 million is current.

At September 27, 2015 , the Company’s reserves for environmental remediation obligations totaled $9.1 million , of which $5.0 million is included in current accrued liabilities. The Company periodically evaluates whether it may be able to recover a portion of future costs for environmental liabilities from its insurance carriers and from third parties. The timing of expenditures depends on a number of factors that vary by site, including the nature and extent of contamination, the number of potentially responsible parties, the timing of regulatory approvals, the complexity of the investigation and remediation, and the standards for remediation. The Company expects that it will expend present accruals over many years and will complete remediation of all sites with which it has been identified in up to 30 years . A number of other lawsuits, claims and proceedings have been or may be asserted against the Company, including those pertaining to product liability, acquisitions, patent infringement, commercial contracts, environmental, employment and employee benefits matters. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial statements.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers , which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In July 2015, the FASB deferred the effective date by one year, but will allow early adoption as of the original adoption date. This new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is currently in the process of determining its implementation approach and assessing the impact on the consolidated financial statements and footnote disclosures.
