Abstract

Extremely light efficient optical correlators can be built if both the input and filter are displayed on phase modulating devices. Problems may exist, however, since changes in the input scene intensity cause changes in the phase encoding. An analysis is presented here for the VanderLugt correlator architecture. Experimental results comparing the correlator response to phase-encoded and amplitude-encoded inputs are also presented for varying input scene intensities.
