Abstract

We have proposed and demonstrated a shift-invariant optical associative memory by the modified Hausler/Lange algorithm. It is a feedback network with space invariant coupling by the convolution operation. The system is shown to have the capabilities of error correction and pattern recognition. Both computer simulations and optical experiments are presented in this paper.
