物像互遮掩的彩虹全息记录

提出了一种使多个物体的再现像间有相互遮掩效果的彩虹全息记录方法。在主全息图记录光路中设置系列互补的挡光屏，对不同的物体分别进行记录；所得到的彩虹全息图再现时，左右移动观察，将看到不同物体的再现像在视场中逐渐交替出现，沿挡光屏边缘相互遮掩。给出了挡光屏的设置参数，并完成了“天狗袭日”彩虹全息图的设计和制作，获得了满意的效果。

Rainbow Hologram with Hiding Effect

A method of recording rainbow hologram using hiding effect between the recorded object’s images is proposed. A series of complementary sheltering screens are placed in the optical path of the master hologram. The varied objects are recorded respectively by means of different screens. When the obtained rainbow hologram is reconstucted, the varied images will be displayed or hidden one another along with the rainbow hologram displaced horizontally. The setting parameters of the complementary sheltering screen and the experimental example are given in this paper. The experimental result is very satisfactory.
