Abstract

An experimental demonstration of a holographic associative memory is presented. The system utilizes an array of classic VanderLugt correlators to implement in parallel the inner product between an input and a set of stored reference images. Each inner product is used to read out an associated image. Theoretical analysis of the system is given, and experimental results are shown.
