Angle-multiplexing recording of multi-context for optically reconfigurable gate array in holographic memory using liquid crystal composites

A holographic polymer-dispersed liquid crystal (HPDLC) memory to record multi-context information for an optically reconfigurable gate array is formed by the angle-multiplexing recording using successive laser exposures in liquid crystal (LC) composites. The laser illumination system is constructed using the half mirror and photomask written by the different configuration contexts placed on the motorized stages under the control of a personal computer. The configuration contexts corresponding to the various logical circuits are reconstructed by the laser illumination at different incident angle in the HPDLC memory.
