Holographic information retrieval system.
We describe in this paper the organization and operation of an exploratory holographic library information processing system successfully demonstrated in our laboratory. This system consists of a recording stage and an information-retrieval and readout stage, all of which are controlled by a minicomputer. Abstracts of literature are stored in hologram arrays on 35-mm roll film. A new technique of holographic correlation detection that is appropriate for parallel processing is used for interrogations with arbitrary words, and it results in the remarkable reduction in the loads of the minicomputer and its interface to the optical system.
