Abstract

An optical implementation of a spatial light modulator based Hopfield type optical associative memory [1] is introduced. An inner-product scheme [2-5] is utilized in the optical system architecture such that the synapses matrix is realized by storing the memory images in two separated spatial light modulators placed in tandem. This scheme is able to save the memory storage space by up to one order of magnitude and is thus very suitable for optical implementation using spatial light modulators.
