| 摘 要： | 本文对几种不同类型的明胶对DCG全息图的衍射效率的影响进行了研究。发现不同类型的明胶对DCG全息图的衍射效率的影响差异较大。活性胶,最高衍射效率可达80%以上,全息图的透明度很好;改性胶,衍射效率在60～80%之间,全息图上易产生“白雾”;惰性明胶,虽可得到透明清晰的全息图,但最高衍射效率一般不超过50%.

| Abstract: | The effect of seven different gelatins on diffraction efficiency of dichromated gelatin holograms was studied. It was found that one gelatin differs greatly from another in diffraction efficiency of dichromated gelatin holograms. Highest diffraction efficiencies of dichromated gelatin holograms of active gelatins are over 80 percent and that of PA modified gelatin is between 60 and 80 percent and those of inert gelatins are below 50 percent. Dichromated gelatin holograms of active and inert gelatins are clear, but that of PA modified gelatin has “white fog”. |
