✦ Synopsis
We solve Maxwell's equations for the intensity proÿle of holograms recorded in a photo-sensitive material. The solution shows that interpage crosstalk noise is absent when the address codes used to reference the holograms are delta-correlated instead of orthogonal. We also develop a technique by which pseudorandom codes, which are delta-correlated, can be generated. We demonstrate both numerically and experimentally that these pseudorandom codes yield good hologram reconstruction and bounded interpage crosstalk noise.
