Abstract
The results of the synthesis and investigation of two special kinds of thick-layered self-developing glycerol- containing dichromated gelatin are presented. One type was sensitive to blue light while the other type with methylene blue additions was red-sensitive. The thickness of the layers varied from 0.1 to 2 mm. The holographic characteristics are discussed. The method for 3D data storage by means of multiplexing 3D speckle-shift holograms when using counterpropagating beam hologram recording is presented. The method permits hologram multiplexing by shifting a speckle wave by the value equal to its correlation radius. The number of multiplexed holograms and lifetime of holograms are discussed.
