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 related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended January 3, 2016 (“ 2015 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 October 2, 2016 and the consolidated results of operations and consolidated comprehensive income for the three and nine months then ended and cash flows for the nine months then ended. The results of operations and cash flows for the periods ended October 2, 2016 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. In the third quarter of 2016, Teledyne sold assets of the Printed Circuit Technology (“PCT”) business for $ 9.3 million in cash. As a result, these financial statements reflect the classification of our PCT business as a discontinued operation. See Note 14 to these condensed consolidated financial statements for additional information. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. The ASU is intended to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted for any entity in any interim or annual period. Teledyne elected to adopt early this ASU in the third quarter of 2016, therefore Teledyne is required to report the material impacts of this standard as though the ASU had been adopted at the beginning of the fiscal year. Accordingly, Teledyne recognized additional income tax benefits as an increase to net income of $ 4.0 million and $ 5.8 million during the third quarter and nine months ended October 2, 2016. The adjustments for the third quarter included only the quarterly impacts, whereas the adjustments for the first nine months of 2016 include the first and second quarter additional income tax benefits of $ 0.6 million and $ 1.2 million , respectively and the immaterial impact for reclassification of amounts from financing activities to operating activities in the condensed consolidated statement of cash flows. Teledyne has elected to record forfeitures as they occur, which did not have a material impact on the condensed consolidated financial results. The new guidance did not impact any periods prior to our 2016 fiscal year, as the changes were applied on a prospective basis. In May 2014, the FASB issued 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 evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. The new guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new guidance must be adopted using a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.

Business Combinations and Investments, Goodwill and Acquired Intangible Assets [Abstract]
Business Combinations, Dispositions, Goodwill and Acquired Intangible Assets	Business Combinations, Dispositions, Goodwill and Acquired Intangible Assets On May 3, 2016, Teledyne DALSA, Inc., a Canadian-based subsidiary, acquired the assets and business of CARIS, Inc. (“CARIS”) for an initial cash payment of $ 26.6 million , net of cash acquired. Teledyne received a $ 0.4 million purchase price adjustment in the fourth quarter of 2016. Based in Fredericton, New Brunswick, Canada, CARIS is a leading developer of geospatial software designed for the hydrographic and marine community and is part of the Digital Imaging segment. On April 15, 2016, Teledyne LeCroy, Inc., a U.S.-based subsidiary, acquired assets of Quantum Data, Inc. (“Quantum Data”) for $ 17.3 million in cash. Based in Elgin, Illinois, Quantum Data provides electronic test and measurement instrumentation and is a market leader in video protocol analysis test tools. On April 6, 2016, Teledyne LeCroy, Inc. also acquired Frontline Test Equipment, Inc. (“Frontline”) for $ 13.7 million in cash. Based in Charlottesville, Virginia, Frontline provides electronic test and measurement instrumentation and is a market leader in wireless protocol analysis test tools. Quantum Data and Frontline are part of the Instrumentation segment. Teledyne spent $ 66.7 million on acquisitions and other investments in 2015, of which $ 63.7 million was spent in the first nine months of 2015. In June 2015, Teledyne DALSA BV, a Netherlands-based subsidiary, acquired Industrial Control Machines SA. In April 2015, Teledyne DALSA, Inc. acquired the remaining 49% noncontrolling interest in the parent company of Optech Incorporated. On February 2015, Teledyne acquired Bowtech Products Limited through a U.K.-based subsidiary. Also in 2016 and 2015, Teledyne made additional investments in Ocean Aero, Inc. Teledyne funded the purchases from borrowings under its credit facility and cash on hand. 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 January 3, 2016 , please refer to Note 3 of our 2015 Form 10-K. Teledyne’s goodwill was $1,183.5 million at October 2, 2016 and $1,140.2 million at January 3, 2016 . The increase in the balance of goodwill in 2016 included $ 40.5 million in goodwill from recent acquisitions and also the impact of exchange rate changes. Goodwill from the 2016 acquisitions will be deductible for tax purposes. Teledyne’s net acquired intangible assets were $237.7 million at October 2, 2016 and $243.3 million at January 3, 2016 . The decrease in the balance of acquired intangible assets in 2016 reflected $ 21.5 million of amortization, partially offset by $ 15.6 million of intangible assets from recent acquisitions. The Company is 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 2016 acquisitions. The Company made preliminary estimates as of October 2, 2016 since there was insufficient time between the acquisition dates and the end of the period to finalize the analysis. See Note 14 to these condensed consolidated financial statements for additional information on the sale of the PCT business. In the second quarter of 2016, Teledyne sold a former operating facility in California for net proceeds of $ 19.5 million . The gain on the sale of $ 17.9 million is included in other income. In conjunction with the sale of this former operating facility, Teledyne entered into a like-kind exchange agreement under Section 1031 of the U.S. Internal Revenue Code with a qualified intermediary. Pursuant to the like-kind exchange agreement, the net proceeds of $ 19.5 million were placed into an escrow account administered by a qualified intermediary. Accordingly, the net proceeds of $ 19.5 million were classified as restricted cash on the condensed consolidated balance sheet as of October 2, 2016. On October 14, 2016, Teledyne completed the Section 1031 like-kind real estate exchange and the restricted cash was used in the transaction.

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. 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. 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 for our Canadian companies, including DALSA. 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 gains recorded in AOCI, net of tax, for contracts that will mature in the next twelve months total $0.1 million . These gains are expected to be offset by anticipated losses 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 October 2, 2016 , Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $62.7 million . These foreign currency forward contracts have maturities ranging from December 2016 to February 2018. The effect of derivative instruments designated as cash flow hedges in the condensed consolidated financial statements for the third quarter and nine months ended October 2, 2016 and September 27, 2015 was as follows (in millions): Third Quarter Nine Months 2016 2015 2016 2015 Net gain (loss) recognized in AOCI (a) $ (1.0 ) $ (4.2 ) $ 3.4 $ (8.2 ) Net gain (loss) reclassified from AOCI into cost of sales (a) $ (0.1 ) $ (2.4 ) $ 2.9 $ (5.6 ) Net foreign exchange gain (loss) recognized in other income and expense (b) $ 0.1 $ (0.1 ) $ (0.2 ) $ 0.2 a) Effective portion, pre-tax b) Amount excluded from effectiveness testing 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 October 2, 2016 , 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$ 23.5 U.S. Dollars US$ 18.0 Canadian Dollars C$ 11.4 Euros € 7.8 Euros € 14.4 U.S. Dollars US$ 16.1 Great Britain Pounds £ 1.4 Australian Dollars A$ 2.4 Great Britain Pounds £ 41.4 U.S. Dollars US$ 54.4 Singapore Dollars S$ 1.7 U.S. Dollars US$ 1.3 U.S. Dollars US$ 0.7 Japanese Yen ¥ 75.0 The above table includes non-designated hedges derived from terms contained in triggered or previously designated cash flow hedges. 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. Teledyne does not use foreign currency forward contracts for speculative or trading purposes. 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 October 2, 2016 was expense of $1.3 million and $0.9 million , respectively.

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. The calculation of diluted earnings per share is based on the weighted average number of common shares outstanding increased by contingent dilutive shares that could be issued under: 1) various compensation plans, including the dilutive effect of stock options based on the treasury stock method, and 2) the forward contract feature of the accelerated repurchase program. On February 2, 2015, the Company entered into a $ 142.0 million accelerated share repurchase (“ASR”) agreement with a financial institution (“ASR Counterparty”) in a privately negotiated transaction for 1,500,000 shares of the Company's common stock. 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. In November 2015, the February 2015 ASR was settled with the Company making a payment of $ 1.2 million . In November 2015, the Company entered into a $ 100.5 million ASR agreement with a financial institution in a privately negotiated transaction for 1,100,000 shares of the Company's common stock. Pursuant to the ASR agreement, the Company advanced $ 100.5 million to the ASR Counterparty and received 1,045,000 shares of common stock. On February 19, 2016, the November 2015 ASR was settled and Teledyne received 135,374 shares of common stock. In 2015, the Company spent a total of $ 243.8 million to repurchase a total of 2,561,815 shares of its common stock. On January 26, 2016, the Company’s Board of Directors authorized an additional stock repurchase program authorizing the Company to repurchase up to an additional 3,000,000 shares of its common stock. The 2015 and 2016 stock repurchase authorizations are expected to remain open continuously, with respect to the shares remaining thereunder, 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. No repurchases have been made under this authorization in 2016. For a further description of the Company’s stock repurchase program, please refer to Note 8 of the 2015 Form 10-K. For the third quarter of 2016, no stock options were excluded in the computation of diluted earnings per share. For the first nine months of 2016 , 336,457 stock options were excluded in the computation of diluted earnings per share because they had exercise prices that were greater than the weighted average market price of the Company’s common stock during the period. For the third quarter and the first nine months of 2015 , no stock options were excluded in the computation of diluted earnings per share. The weighted average number of common shares used in the calculation of basic and diluted earnings per share consisted of the following (in millions): Third Quarter Nine Months 2016 2015 2016 2015 Weighted average basic common shares outstanding 34.7 35.3 34.5 35.4 Effect of dilutive securities 0.9 0.8 0.9 0.8 Weighted average diluted common shares outstanding 35.6 36.1 35.4 36.2

Stock option compensation expense was $2.6 million and $ 9.7 million for the third quarter and first nine months of 2015. Employee stock option grants are charged to expense evenly over the three year vesting period. For 2016 , the Company currently expects approximately $11.5 million in stock option compensation expense based on stock options currently outstanding. This amount can be impacted by employee retirements and terminations or stock options granted during the remainder of the year. The Company issues shares of common stock upon the exercise of stock options. No stock options were granted in 2015.

Inventory Disclosure [Abstract]
Inventories	Inventories Inventories are stated at current cost net of reserves for excess, slow moving and obsolete inventory, 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 $235.8 million at October 2, 2016 and $239.0 million at January 3, 2016 . The remainder of the inventories using the LIFO method were $110.0 million at October 2, 2016 and $91.6 million at January 3, 2016 . 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. Balance at Inventories (in millions): October 2, 2016 January 3, 2016 Raw materials and supplies $ 147.4 $ 139.1 Work in process 156.3 146.1 Finished goods 42.1 45.4 345.8 330.6 Progress payments (7.2 ) (12.3 ) Reduction to LIFO cost basis (13.6 ) (14.2 ) Total inventories, net $ 325.0 $ 304.1

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 2016 was 17.2% and 24.1% , respectively. The Company’s effective income tax rate for the third quarter and first nine months of 2015 was 21.8% and 26.4% , respectively. The third quarter of 2016 included net discrete income tax benefits of $6.6 million compared with net discrete income tax benefits of $7.4 million for the third quarter of 2015 . The first nine months of 2016 included $ 1.5 million in net discrete income tax benefits, compared with net discrete income tax benefits of $ 8.5 million for the first nine months of 2015. The net discrete income tax benefit for the first nine months of 2016 includes $ 6.7 million in income tax expense related to the $ 17.9 million gain on the sale of the former operating facility. In addition, in the third quarter of 2016, Teledyne elected to adopt ASU 2016-09, which is in advance of the mandatory 2017 effective date and includes a change in accounting for income taxes associated with share-based compensation. Teledyne is required to report the impacts as though the ASU had been adopted at the beginning of its 2016 fiscal year. As a result of the early adoption, in the third quarter of 2016, Teledyne recorded a $ 4.0 million income tax benefit. The tax benefit related to the adoption for the first and second quarters of 2016, was $ 0.6 million and $ 1.2 million , respectively. Excluding net discrete income tax items in both periods, and the gain and related taxes on the facility sale in 2016, the effective tax rates would have been 27.5% for the third quarter and 27.6% for the first nine months of 2016 and 33.5% for the third quarter and 30.9% for the first nine months of 2015.

At October 2, 2016 , the Company’s reserves for environmental remediation obligations totaled $7.8 million , of which $4.6 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, 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.

Discontinued Operations	Discontinued Operations In the third quarter of 2016, Teledyne completed the disposition of the net assets of its PCT business for $ 9.3 million in cash, resulting in no gain or loss. The sale represented a disposition of a component that was outside the Company’s current strategy and met the criteria to be classified as held for sale in the second quarter. As such, the PCT component met the criteria to be classified within discontinued operations during the second quarter of 2016. Prior to being classified within discontinued operations, PCT was included in the Aerospace and Defense Electronics segment. In connection with the sale, the Company entered into a transition services agreement, effective July 8, 2016, to provide certain services to facilitate the orderly transfer of the business operations to the buyer, with the transition services agreement expected to continue through the first quarter of 2017.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. The ASU is intended to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted for any entity in any interim or annual period. Teledyne elected to adopt early this ASU in the third quarter of 2016, therefore Teledyne is required to report the material impacts of this standard as though the ASU had been adopted at the beginning of the fiscal year. Accordingly, Teledyne recognized additional income tax benefits as an increase to net income of $ 4.0 million and $ 5.8 million during the third quarter and nine months ended October 2, 2016. The adjustments for the third quarter included only the quarterly impacts, whereas the adjustments for the first nine months of 2016 include the first and second quarter additional income tax benefits of $ 0.6 million and $ 1.2 million , respectively and the immaterial impact for reclassification of amounts from financing activities to operating activities in the condensed consolidated statement of cash flows. Teledyne has elected to record forfeitures as they occur, which did not have a material impact on the condensed consolidated financial results. The new guidance did not impact any periods prior to our 2016 fiscal year, as the changes were applied on a prospective basis. In May 2014, the FASB issued 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 evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. The new guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new guidance must be adopted using a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented. The Company is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.
