Paper 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.
