Paper Abstract

The attractive possibilities offered by volume holography, with discrimination between superimposed holograms by means of Bragg Angle selection, have stimulated much searching for photosensitive materials that permit erasable storage as well as nondestructive retrieval. The dichroism of FA centers in KC1:Na offers close to optimum optical behavior for holographic storage and retrieval, and especially a bidirectional photochromic response such that information storage without change in the overall optical density can be accomplished. High speed random access to information is a dircct consequence of the large information packing density iesulting from many superimposed holograms per unit volume. Unusually ,low noise and error rate is a unique characteristic of the particular material and storage technique employed.
