从微观化学结构分析全息图的环境稳定性

AN ANALYSIS OF HOLOGRAMS ENVIRONMENTAL STABILITY BASED ON MICROPHOTOCHEMICAL STRUCTURE

根据实验结果,分析比较了用两种交联型重铬酸盐全息记录材料(重铬酸盐明胶和无明胶重铬酸盐全息软片)制作的全息图的内部光化学反应产物的微观化学结构,对二者在抗潮能力和环境稳定性方面表现出的显著差异作了比较合理的理论解释.提出的观点是:全息图具有良好的抗潮能力和环境稳定性的根本原因在于光化学反应产物的内部化学结构的完全对称性.

Based on experimental result, the microphotochemical structures of DCG holograms and NGD holograms are analysed comparatively. A reseanable explaination to the great difference between these two kinds of holograms, in antihumidity and environmental stability, is given. A suggestion that the symmetry of microphotochemical structure of chelate be the essential of good antihumidity and environmental stability of holograms is proposed.
