Paper Abstract

The results of realization of linear phase coefficient composite (LPCC) filters in 4-f correlator are presented in this paper. LPCC filters application allows achieving invariance of correlation peak in the presence of geometric distortions of contour objects. Invariant correlation filters were synthesized as amplitude holograms with continuous transparency and realized as binary amplitude holograms. The results of correlator signals modeling for the cases with different numbers of hologram counts which used to represent grayscale level gradation are presented.
