Thick absorption recording media in holography.

The response of holograms recorded in thick absorption media is evaluated in terms of diffraction efficiency, angular orientation sensitivity, and wavelength sensitivity. Calculated results showing the relation between these measures of response and various hologram recording parameters are presented. These calculations are supported with experimental data obtained with thick photographic emulsions and various photochromic materials. In addition, experimental results are given which demonstrate the use of thick recording media in holographic data storage and multicolor wavefront reconstruction.
