Effect of laser exposure condition on formation of holographic memory by angle-multiplexing recording using liquid crystal composites

The effect of laser exposure condition on the formation of holographic polymer-dispersed liquid crystal (HPDLC) memory by the angle-multiplexing recording is discussed. The successive laser illumination system to record the various configuration contexts at the different region and angle in HPDLC memory is constructed by controlling the laser interference exposure in liquid crystal (LC) composites and the optical equipment using the motorized stages.
