Influence of phase masks on cross talk in holographic memory

Abstract

Interpixel cross talk that is due to diffraction and aberrations is, to some extent, unavoidable because of trade-offs in the design of holographic storage systems. Phase masks have been proposed to avoid problems encountered in Fourier-transform holographic recording, but they have other effects on pixel cross talk. We investigate the effect of using phase masks in the data-bearing object beam on the output interpixel cross talk in a holographic memory system.
