Holographic 3-D disks using shift multiplexing

Abstract

Summary form only given. Recently, we demonstrated holographic recording in a 100-micron-thick photopolymer, achieving a surface density of 10 bits//spl mu/m/sup 2/, by recording a combination of peristrophic and angle-multiplexed holograms. We would like to further increase the capacity of this system by storing data at many different locations. One simple implementation of such system would be a holographic 3-D disk, where the disk spins so that holograms stored at different locations on the disk could be accessed. We will use a new multiplexing method (shift multiplexing) that is especially well suited for the holographic disk configuration.
