Abstract

Optical symbolic substitution offers general purpose optical processors for numeric, logic, and image processing functions. Its realization on an optical correlator is most attractive. This paper addresses the optical laboratory realization of the symbolic substitution steps of recognition and substitution with attention to the effects of the beam balance ratio (K-ratio) used when synthesizing the matched spatial filters for a symbolic substitution correlator. Specifically, low spatial frequencies should be emphasized in the substitution step and high spatial frequencies should be emphasized in the recognition step.
