Dependence of angular selectivity of thick phase transmission hologram recorded in dichromated gelatin film on processing parameters

摘要

Based on the theoretical investigation using coupled wave theory it is shown that large thickness and high depth of refractive index modulation are quite promising for page-oriented Bragg-selective holographic optical memory recorded in dichromated gelatin film. Whereas, low thickness and high depth of refractive index modulation are desirable for wide angle coherent imaging and concentrating system for photovoltaic power generation with appreciable tolerance angle.
