摘要：

Based on the known diffraction property of an elementary volume grating and on the linear superposition assumption of the diffracted wave field, we propose in this paper a simple method to analyze the cross-talk noise in an angle multiplexing holographic memory. The variation of the angular selectivity of stored volume holograms due to the change of the incident angles of both the signal and the reference beams is considered. It is found that the cross-talk noise varies with the order of the retrieved hologram in an oscillation fashion. The highest cross-talk noise given in this paper is lager than that given previously and should be approximated by a piecewise linear or quadratic function of the storage capacity, rather than by a simple linear function. The effect of increasing the angular separation between the reference beams of adjacent holograms on the cross-talk performance is discussed.
