Abstract

Hardened dichromated gelatin is the best material available today for the fabrication of holographic optical elements (HOEs) because of its low scattering, large refractive index modulation capacity, and other unique properties such as reprocessibility. On the basis of experimental data accumulated during the last several years, we describe holographic characteristics of the dichromated gelatin, including exposure characteristics with a bulk exposure model, hologram thickness change, and environmental stability. Basic chemistry, hologram formation in the dichromated gelatin, and generalized processing techniques are also discussed.

摘要

硬化重铬酸盐明胶因其低散射、大折射率调制能力以及诸如可再加工性等其他独特性能,是当今用于制造全息光学元件(HOE)的最佳材料。基于过去几年积累的实验数据,我们描述了重铬酸盐明胶的全息特性,包括采用体曝光模型的曝光特性、全息图厚度变化以及环境稳定性。还讨论了基本化学、重铬酸盐明胶中的全息图形成以及通用加工技术。
