Paper Abstract

We have stored up to 5,000 holograms of high-resolution images (320 X 220 pixels) within a single crystal of Fe:LiNbO3. This storage capacity permits the construction of a processor which can compute all the inner-products between any input image and the stored images simultaneously. Without having to retrieve information from a secondary mass memory, overall computation speed of inner-products can be very high. In this paper, we will describe our architecture; address performance issues; and present experimental results on reconstruction of holograms and inner-product computation.
