摘要：

A new technique is presented that improves the results of associative recall in a volume holographic memory system A background is added to the normal search argument to increase the amount of optical power that is used to reconstruct the reference beams in the crystal. This is combined with post-processing of the captured image of the reference beams. The use of both the background and post-processing greatly improves the results by allowing associative recall using small arguments. In addition, the number of false hits is reduced and misses are virtually eliminated. (C) 1999 Elsevier Science B.V. All rights reserved.
