摘要

Abstract: In this paper the principle and storage capacity of spatioangularly multiplexed holographic data (SAMHD), by incorporating spherical reference beams into spatioangular multiplexing scheme, are described. The spatial selectivity of SAMHD is derived, based on its angular selectivity, by a simplified ray-optics method. The main advantage of SAMHD over the conventional block-oriented holographic storage is that the optical system for write/read of a disk would be much more simple. Preliminary experiments showing good agreement with theoretical analysis are presented.!4
