Paper Abstract

We discuss a method for the recording of multiple images in a photorefractive LiNbO3 crystal which needs only a single object beam without any reference beam. The object beam is modulated by a lenticular lens array sheet to produce a set of sub-object beams. These beams are angularly separated on the recording plane but are made to overlap by light scattered light by the photorefractive LiNbO3 crystal. The result is that only a single beam is needed to record multiple holograms. Experimental results show that four holograms can be stored in a photorefractive LiNbO3:Fe crystal 30 mm X 30 mm X 1 mm in size at the same time. The proposed method makes it especially simple to produce one-beam write/read multiple holograms.
