Abstract

A method for the computer holographic codification of composite real filters is presented. This is especially useful for the optical implementation of the correlation in pattern recognition using the joint-transform scheme. Numerical and experimental results of the performances of some of these filters are shown for simple binary objects and for more realistic grey tone ones.
