Spinning disc volume holographic memory

摘要: A volume holographic memory has a spinning disk comprised of photorefractive medium, object beam optics configured to direct an through the outer edge disk, and reference simultaneously disk. An angle multiplexer manipulates facilitate formation multiplexed holograms. The cooperate within medium sequentially form plurality sets holograms therein while is spinning. phase conjugator directs conjugate back after previously passed therethrough, so as read-out. Amplitude monitoring provided use exposure schedule. Path length assures consistent relationship between beams for write erase operations. Calibration provided.
