Abstract

Dichromated Gelatin (DCG) was first used in optics in 1872 by Lord Rayleigh. Then, in 1968, Shankoff suggested its use as a photosensitive material to record interference diffraction gratings and holograms. Diffraction efficiencies of nearly 100% were achieved. This review discusses some physical and chemical characteristics of DCG films; the fabrication methods of DCG films; and some of the applications of DCG films in holography, holography in real time, solar concentrators, optical elements, and relative humidity sensors.

摘要

重铬酸盐明胶（DCG）于1872年由瑞利勋爵首次用于光学领域。然后，在1968年，尚科夫建议将其用作记录干涉衍射光栅和全息图的光敏材料。实现了近100%的衍射效率。本文综述了DCG薄膜的一些物理和化学特性、DCG薄膜的制备方法，以及DCG薄膜在全息术、实时全息术、太阳能聚光器、光学元件和相对湿度传感器中的一些应用。
