Abstract
The invention provides a system with no moving parts for autocorrelating optical radiation signals. An incident optical radiation signal is first divided into first and second optical beams which, in the preferred embodiment, are directed respectively through first and second electro-optic crystals to produce a relative time adjustment between the optical beams. The optical beams are then combined and a product value is determined. Using the technique of autocorrelation, the product of the optical beams is measured over a range of time adjustments between the optical beams to provide a measurement of the incident optical radiation signal. The system and method described provide a vibration-free technique for autocorrelation which can be incorporated into laser resonator structures.
