摘要： 重铬酸盐明胶(DCG)是全息照相的重要材料,全息图的形成过程是六价铬在光的激发下与明胶分子的某些基团发生反应,还原为三价铬;三价铬再与明胶分子的某些基团形成配键使明胶交联,产生折射率调制而成像.某些物理、化学参数怎样影响这一过程尚不十分清楚.

Abstract: The photochemical reaction of dichromated gelatin was studied by laser photoa-coustic spectroscopy,Results show that the solid-state reaction of the dichromate withgelatin obeys Watanabe-Westheimer reaction scheme. The photosensitivity of dichromatedgelatin is dependent on pH and concentration of dichromate solution.

Key words: dichromated gelatin, photochemical reaction, laser photoacoustic spectrum
