重铬酸盐明胶反射全息图再现波长红移的研究

Study on the Shift to Red Light of the Reconstruction Wavelength of Reflection Hologram in Dichromated Gelatin

采用与传统明胶膜不同的制备方法及后处理过程，实现对明胶膜膨胀的控制．使用重铬酸盐明胶记录的反射全息图再现波长红移。这一研究对于用重铅酸盐明胶制作真彩色全息图某些全息光学元件是很有意义的。

In a different way from the traditional preparation of DCG gclatin flim and the control of gelatin film's swelling during the postprocession, the reflection hologram recorded in bluegreen light is used to show the reconstruction wavelength's shift to red light. This study is very inter esting for making true color holograms and holographic optical elements.
