Abstract

An investigation of the stability of the diffraction efficiency of dichromated gelatin (DCG) holograms has been carried out paying specific attention to coated and baked holograms that are subsequently exposed to high humidity (RH > 60%) environment. The investigation has revealed that (a) the environmental stability of DCG holograms can be considerably improved either by coating or baking; (b) the DCG holograms can be used at temperatures well-above room temperature (for example, as high as 175 degrees C) without showing undue detrimental effects regarding their efficiency; and (c) the diffraction efficiency of uncoated and baked holograms can be restored by reprocessing whereas such a thing becomes impossible in coated holograms.

摘要

对重铬酸盐明胶（DCG）全息图衍射效率的稳定性进行了研究，特别关注了涂覆和烘焙后的全息图，这些全息图随后暴露在高湿度（相对湿度>60%）环境中。研究表明：（a）通过涂覆或烘焙可以显著提高DCG全息图的环境稳定性；（b）DCG全息图可以在远高于室温的温度下使用（例如，高达175摄氏度），而不会对其效率产生过度的不利影响；（c）未涂覆和烘焙的全息图的衍射效率可以通过再处理恢复，而在涂覆的全息图中则无法做到这一点。
