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 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 April 3, 2016 and the consolidated results of operations and consolidated comprehensive income and cash flows for the three months then ended. The results of operations and cash flows for the period ended April 3, 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. 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. In March 2016, the FASB Issued 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. The Company is currently evaluating the impact this guidance will have on its 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 leasing standard will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard 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 of adopting this guidance on its on the consolidated financial statements and footnote disclosures.

Business Combinations and Investments, Goodwill and Acquired Intangible Assets [Abstract]
Business Combinations, Investments, Goodwill and Acquired Intangible Assets	Business Combinations, Investments, Goodwill and Acquired Intangible Assets In the first quarter of 2016, Teledyne did not make any acquisitions, however, in the second quarter of 2016, Teledyne completed the acquisitions of two test and measurement instrumentation companies and one imaging software company for initial aggregate cash consideration of $ 60.0 million . Teledyne spent $ 66.7 million on acquisitions and other investments in 2015, of which $ 18.8 million was spent in the first quarter of 2015. In June 2015, Teledyne DALSA BV, a Netherlands-based subsidiary, acquired Industrial Control Machines SA (“ICM”). In April 2015, Teledyne DALSA, Inc. acquired the remaining 49% noncontrolling interest in the parent company of Optech Incorporated (“Optech”). In February 2015, Teledyne acquired Bowtech Products Limited (“Bowtech”) through a U.K.-based subsidiary. Also in 2015, Teledyne made an additional investment in Ocean Aero, Inc. (“Ocean Aero”). 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 $1,151.9 million at April 3, 2016 and $1,140.2 million at January 3, 2016 . The increase in the balance of goodwill in 2016 resulted from the impact of exchange rate changes. Teledyne’s net acquired intangible assets were $240.0 million at April 3, 2016 and $243.3 million at January 3, 2016 . The decrease in the balance of acquired intangible assets in 2016 resulted from amortization, partially offset by the impact of exchange rate changes.

Derivative Instruments

Derivative Instruments	3 Months Ended
	Apr. 03, 2016
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 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 losses recorded in AOCI, net of tax, for contracts that will mature in the next twelve months total $0.2 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 April 3, 2016 , Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $73.2 million . These foreign currency forward contracts have maturities ranging from June 2016 to February 2018. Non-Designated Hedging Activities In addition, the Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign-currency-denominated monetary assets and liabilities, including intercompany receivables and payables. As of April 3, 2016 , Teledyne had foreign currency contracts of this type in the following pairs (in millions): Contracts to Buy Contracts to Sell Currency Amount Currency Amount Canadian Dollars C$ 55.8 U.S. Dollars US$ 41.7 Canadian Dollars C$ 10.6 Euros € 6.9 Euros € 7.1 U.S. Dollars US$ 8.0 Great Britain Pounds £ 1.1 Australian Dollars A$ 2.2 Great Britain Pounds £ 21.5 U.S. Dollars US$ 31.4 Singapore Dollars S$ 1.7 U.S. Dollars US$ 1.2 U.S. Dollars US$ 2.2 Japanese Yen ¥ 250.0 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 under ASC 815, Derivatives and Hedging ("ASC 815"), 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 first quarter ended April 3, 2016 and March 29, 2015 was as follows (in millions): First Quarter 2016 2015 Net gain (loss) recognized in AOCI (a) $ 4.0 $ (4.6 ) Net loss reclassified from AOCI into cost of sales (a) $ (2.2 ) $ (1.4 ) Net foreign exchange gain (loss) recognized in other income and expense (b) $ (0.2 ) $ 0.2 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 first quarter ended April 3, 2016 was income of $2.7 million and expense of $4.9 million for the first quarter ended March 29, 2015. Fair Value of Derivative Financial Instruments The fair values of the Company’s derivative financial instruments are presented below. All fair values for these derivatives were measured using Level 2 information as defined by the accounting standard hierarchy (in millions): Asset/(Liability) Derivatives Balance sheet location April 3, 2016 January 3, 2016 Derivatives designated as hedging instruments: Cash flow forward contracts Other assets $ 0.8 $ — Cash flow forward contracts Accrued liabilities — (4.7 ) Cash flow forward contracts Other long-term liabilities (0.8 ) (1.3 ) Total derivatives designated as hedging instruments — (6.0 ) Derivatives not designated as hedging instruments: Non-designated forward contracts Other current assets 2.8 0.2 Non-designated forward contracts Accrued liabilities (1.8 ) (6.0 ) Total derivatives not designated as hedging instruments 1.0 (5.8 ) Total asset (liability) derivatives $ 1.0 $ (11.8 )

Earnings Per Share

Earnings Per Share	3 Months Ended
	Apr. 03, 2016
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. For a further description of the Company’s stock repurchase program, please refer to Note 8 of our 2015 Form 10-K. For the first quarter of 2016 , 510,476 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. In the first quarter of 2015 , no stock options were excluded in the computation of diluted earnings per share. The following table sets forth the computations of basic and diluted earnings per share (amounts in millions, except per share data): First Quarter 2016 2015 Net income attributable to Teledyne $ 38.4 $ 43.7 Basic earnings per share: Weighted average common shares outstanding 34.4 35.7 Basic earnings per common share $ 1.12 $ 1.22 Diluted earnings per share: Weighted average common shares outstanding 34.4 35.7 Effect of dilutive securities 0.5 0.8 Weighted average diluted common shares outstanding 34.9 36.5 Diluted earnings per common share $ 1.10 $ 1.20

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation Plans	Stock-Based Compensation Plans Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock and performance shares to certain employees. The Company also has non-employee director stock compensation plans, pursuant to which non-qualified stock options and common stock, and beginning in 2015 restricted stock units, have been issued to its directors. After 2014, non-employee directors no longer receive non-qualified stock options. Stock Incentive Plan The following disclosures are based on stock options granted to Teledyne’s employees and directors. Stock option compensation expense was $3.3 million for the first quarter of 2016 and $3.8 million for the first quarter of 2015. Employee stock option grants are charged to expense evenly over the three year vesting period. Director stock option grants are charged to expense evenly over the one -year vesting period. For 2016 , the Company currently expects approximately $11.7 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. The following assumptions were used in the valuation of stock options granted in 2016: 2016 Expected volatility 32.7 % Risk-free interest rate 1.5 % Expected life in years 7.2 Expected dividend yield — Weighted average fair value $ 29.93 Stock option transactions for the first quarter ended April 3, 2016 are summarized as follows: 2016 First Quarter Shares Weighted Average Exercise Price Beginning balance 2,383,870 $ 63.74 Granted 518,310 $ 78.40 Exercised (63,968 ) $ 40.44 Canceled (14,706 ) $ 79.60 Ending balance 2,823,506 $ 66.87 Options exercisable at end of period 1,840,740 $ 58.23 Performance Share Plan and Restricted Stock Award Program For the first of three annual distributions of the 2012 to 2014 Performance Share Plan, 1,944 shares of Teledyne common stock were issued in the first quarter of 2015. In the first quarter of 2016, the Company issued 864 shares and 1,883 shares remain to be issued in 2017. In the first quarter of 2016, the restriction was removed for 39,568 shares of Teledyne common stock related to the 2013 to 2015 Restricted Stock Award Program.

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 $242.3 million at April 3, 2016 and $240.2 million at January 3, 2016 . The remainder of the inventories using the LIFO method were $104.1 million at April 3, 2016 and $96.6 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): April 3, 2016 January 3, 2016 Raw materials and supplies $ 147.2 $ 141.6 Work in process 151.7 149.4 Finished goods 47.5 45.8 346.4 336.8 Progress payments (9.3 ) (12.3 ) Reduction to LIFO cost basis (15.1 ) (15.3 ) Total inventories, net $ 322.0 $ 309.2

Lawsuits, Claims, Commitments, Contingencies and Related Matters	Lawsuits, Claims, Commitments, Contingencies and Related Matters For a further description of the Company’s commitments and contingencies, reference is made to Note 14 of the Company’s financial statements as of and for the fiscal year ended January 3, 2016 , included in our 2015 Form 10-K. At April 3, 2016 , the Company’s reserves for environmental remediation obligations totaled $8.5 million , of which $4.7 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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 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 April 3, 2016 and the consolidated results of operations and consolidated comprehensive income and cash flows for the three months then ended. The results of operations and cash flows for the period ended April 3, 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.
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. In March 2016, the FASB Issued 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. The Company is currently evaluating the impact this guidance will have on its 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 leasing standard will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard 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 of adopting this guidance on its on the consolidated financial statements and footnote disclosures.
