Abstract

Holographic memory is expected as a next- generation optical memory because it potentially has terabyte data capacity per disk and gigabit data transfer rate. Furthermore, when a polarization-sensitive medium is used as a recording medium, a vector wave can be recorded so that few times data capacity and data transfer rate are expected. However, the optical system for the vector wave recording technique such as dualchannel polarization holography[1,2] is complicated. Therefore, simple recording and reconstruction methods have been investigated. In this paper, a digital holographic reconstruction method with spatial phase-shifting is proposed.
