Paper Abstract

This paper contains the results of synthesis and realization of linear phase coefficient composite (LPCC) filters in 4-f correlator. LPCC filters application allows achieving invariance of correlation peak in the presence of geometric distortions of contour objects. LPCC filters were realized as computer generated binary amplitude holograms for application in optical correlator. Experimental results of invariant pattern recognition are presented.
