Abstract

Space-variant logic operations are carried out using an optical parallel processor that is based on polarization encoding and subsequent spatial separation of the encoded light. In this processor a liquid-crystal spatial light modulator is used as an operational kernel that allows a programmable space-variant operation to be performed on a real-time basis by spatially filtering the encoded light pixel by pixel.
