Enhancement of the angular selectivity in encrypted holographic memory

Abstract

Enhancement of the angular selectivity in a double random-phase encoded holographic memory by use of reference plane waves is presented. In the storage algorithm, the angular selectivity is improved with the effect of random-phase masks. We show that the angular selectivity achieved by this scheme is more sensitive than that for Bragg angle detuning in a 90° geometry. Both theoretical and experimental results are presented and analyzed.
