Angle And Space Multiplexed Holographic Storage Using The 90-Degrees Geometry

The 90-degrees geometry - with reference and signal beams entering orthogonal crystal faces - is used to angularly multiplex up to 500 holograms at each of 8 spatially multiplexed locations in a LiNbO3 crystal. A segmented mirror array and a 2D mechanical ...

Method For Holographic Storage Using Peristrophic Multiplexing

Demetri Psaltis

A method of multiplexing holograms by rotating the material or, equivalently, the recording beams is described. Peristropic (Greek for rotation) multiplexing can be combined with other multiplexing methods to increase the storage density of holographic sto ...

Cross-Talk In Phase-Coded Holographic Memories

Demetri Psaltis

The cross talk between holograms multiplexed with Walsh-Hadamard phase codes is analyzed. Each hologram is stored with a reference beam that consists of N phase-coded plane waves. The signal-to-noise ratio (SNR) is calculated for a recording schedule for w ...
