A photorefractive cristal BSO of the sillenite family is used for registering several holograms by angular multiplexing. Each hologram is registered in the crystal modifying the incidence angle of the write-in beams. In the experimental arrangement, the photorefractive crystal BSO is rotated using a step by step motor controlled by a micro-controller. The rotation of the crystal allows to modify the write-in angle. The write-in and read out processes are implemented with a transmission scheme.
