Scheme for implementation of an all-optical non-zero-order joint transform correlator using contrast reversal technique

摘要

Abstract: A technique for realizing an all-optical non-zero order JTC has been proposed and investigated using computer simulation studies. A simple contrast reversal operation forms the basis of the proposed scheme. Effect of quantization and device nonlinearity has been studied to draw closer resemblance to a practical non-zero order image recognition system.!13
