Abstract

The peculiarities of one-dimensional hologram recording in three-dimensional media are considered. The optimum quantity of the hologram superposition is shown to depend on the photolayer thickness. Computer simulation results of the 34-channel recording-reproducing process of twice superposed one-dimensional holograms in the photolayer with the thickness 5 micrometers are presented, the ratio unit signal/zero signal being not less than 8 dB and the recoding density being nearly 108 bit/cm2. The experimental results of the recording investigations with the many-time superpositions (8 exposures) of one-dimensional holograms in the LiNbO3:Fe crystals with the effective thickness nearly 130 micrometers are presented.
