Abstract

The cross-talk noise in hologram memory is analyzed with hybrid multiplexing of the Hadamard phase code and wavelength. The minimum wavelength differences required for obtaining a given signal-to-noise ratio are calculated, as well as the optimum angle between the signal and reference beams for this hybrid multiplexing scheme. Hybrid multiplexing with sufficient wavelength difference is a good method for memory extension in the case of limited-pixel-number spatial light modulators.
