Abstract

Two methods for recording a hologram plate suitable for information search are discussed: consecutive recording of individual items on the same area of a hologram plate and parallel recording of individual identifiers on individual areas of a hologram plate. To increase the number of items to process, the use of a rotating drum is proposed, and experimental results of the sequential search of five hologram plates are shown.
