摘　　要：根据体积全息图的角度复用特性,在一张卤化银干版上记录了多幅图像,再现时轮流显示不同画面从而实现动画显示的效果。设计记录波长632.8nm,再现波长532nm。通过记录和检测光栅确定全息图的处理工艺,从理论上分析了因乳胶收缩导致的光栅结构变化问题,计算得到全息图的记录和再现条件,消除了再现像"左右跳动"的现象,在一张干版上记录了4幅子图。设计并制作完成了自动控制电路和展示装置,实现了三维动画显示效果。According to the multi-angular usable characteristics of the volume hologram, several sub-holograms can be recor- ded in one plate and achieved the animated effect by reconstructing them in turn. The recording and reconstructing wave- lengths are 632.8 nm and 532 nm respectively. The handle process of hologram by recording and measuring grating is ob- tained, and the grating structural changes are analyzed which are caused by the emulsion contraction. The recording and re- constructing conditions of the hologram are calculated, and the problem of ＂left-right＂ jumping phenomenon in reconstruc- ting holograms is solved. Four sub-holograms in one plate are recorded. The automatic control circuit and displaying device which is able to display 3D animated effect are designed.
