Abstract

The orthogonal polarization simultaneous readout technique in a hybrid-multiplexed memory using angular multiplexing and polarization multiplexing is presented. Twenty holograms were hybrid multiplexed in a single LiNbO3 crystal with ten angular positions for angular multiplexing. In each angular position of the holographic memory, two images with orthogonal polarization are multiplexed in the same spatial location inside the LiNbO 3 via polarization multiplexing. These two orthogonally polarized images can be reconstructed simultaneously with a linear polarization reading beam, but they can be separated with a polarization beam splitter, and accordingly each can be viewed independently. The exposure schedule for holographic storage using the proposed hybrid-multiplexing technique is derived.
