Paper Abstract

We have recently developed a new method of multiplexing volume holograms which we call peristrophic multiplexing. The method involves rotation the material, or equivalently, the recording beams. Peristrophic multiplexing can be combined with other multiplexing methods to increase the storage density of holographic storage systems such as holographic 3-D disks. Peristrophic multiplexing has been experimentally demonstrated using DuPont's HRF-150 photopolymer film. A total of 295 holograms were multiplexed at a single location in a 38 micrometers thick photopolymer disk by combining peristrophic multiplexing with conventional angle multiplexing. Application of this new multiplexing method toward a 3-D holographic disk is discussed.
