Sampled dynamic holographic memory

Abstract

We report the experimental demonstration of a photorefractive dynamic holographic memory that has a simple feedback architecture stabilized through a novel spatial sampling technique. By using dynamic copying to compensate for photorefractive decay, this memory provides nondestructive readout, selective erasure and rewriting, and real-time adaptation of holograms through an arbitrarily large number of exposures.
