Paper Abstract

A new experimental system of optical neurocomputing, called optical associatron, is shown. The experimental system has a simple architecture for optical associative memory. Especially, the system has versatile adaptive learning capabilities implemented by using Microchannel Spatial Light Modulators (MSLMs). In this paper, various experimental results of learning and recalling on the experimental system are shown. Based on the results, behavior of learning on the optical associative memory is discussed and a modified method of learning is proposed and verified on the experimental system. In addition, a method of implementation of error back propagation is proposed.
