Holographic data storage system combining shift-multiplexing with peristrophic-multiplexing

Abstract

Holographic data storage (HDS) is a next-generation optical storage that uses the principles of holography. The multiplex holographic recording method is an important factor that affects the recording capacity of this storage. Various multiplex recording methods have been proposed so far. In this study, we focus on shift multiplexing with spherical waves and propose a method of shift multiplex recording that combines the peristrophic multiplexed recording. Simulation and experimental verification shows that the proposed method is effective in principle.
