Abstract

In this paper, a multi-channel associative memory instrumentation prototype was presented, which was divided into two parts spatially. The lower part is a one-channel system using diode-pumped solid-state laser for demonstrating the holographic associative memory miniaturization, while the upper one is a four-channel system for proving the parallel processing architecture. Each channel is actually a photorefractive-based associative memory with external storage and using liquid crystal switch as threshold device in correlation domain.
