General and Supplemental Balance Sheet Information [Abstract]  
Derivatives and Hedging
Under ASC 815, Derivatives and Hedging, 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 Technologies does not use foreign currency forward contracts for speculative or trading purposes.
