摘　　要：在DCG材料记录与消像机理的基础上,通过实验分析确定了后处理过程中最佳的水洗消像和异丙醇逐步脱水干燥的显影技术,实现了DCG全息图彻底“消像”以及记录信息的重新清晰再现.由此展现出了DCG在信息隐藏方面的应用前景.On the basis of recording images on dichromated gelatin （DCG） and image-erasing technique, the optimal image technique of water-washing image-erasing and isopropyl alcohol dehydrating in back-process are found by experimental analysis. As the result, complete image-erasing and clear reappearance of recorded information are accomplished. An extensive prospect of information-hiding in DCG is exhibited.
