holographic memory device and method of mapping the topology periodically alone graphics memory system

摘要

holographic memory system is periodically repeated phase structure of the image plane of the non- lens for near field propagates the Talbot effect utilize . Periodic phase structure in a plane of the holographic memory system alone is mapped to the input data size of the graphics plane memory system . In a preferred embodiment, the interference light is , alone, for the same time on a self- imaging of the spatial light modulator to provide input data to the graphics memory system , passes through the lenslet array , and is propagated through the Talbot effect . Lenslet array is disposed relative to the spatial light modulator , the phase desired image structure from the image pick-up magnetic Fresnel zone size of the input data structure .
