Paper Abstract

An interferometric optical system is configured with an active feedback loop as an optical adaptive filter. The closed loop characteristics of the system are found to be sensitive to alignment and aberrations. An open loop diagnostic procedure is applied to the system to develop stability to a level supporting 30 db adaptively formed frequency rejection notches. The time delay in the closed loop signal path is found to be the limiting factor in system performance.
