Abstract

The design and realization of a compact volume holographic memory using phase-coded multiplexing is described. We present a system capable of storing up to 480 data pages with a resolution of 640 X 480 bits in a single interaction region of a photorefractive LiNbO₃ crystal. A characterization of the key components of the system is given. First experimental results of high-resolution analog image storage as well as the application of the system to real-time optical image processing are presented.
