垂直分割视场制作合成动态全息图

New method of making synthetic dynamic hologram by dividing vertical viewfield

从理论上及实验上分析了利用垂直视场分割法制作合成动态全息图的方法。将二步彩虹全息术中的主全息图Ｈ１分成若干全息单元，在各单元中分别记录了物体一系列连续变化状态的二维图像，利用该主全息图制作像面全息图Ｈ２，从而获得合成动态全息图。该方法用银盐干版记录主全息图Ｈ１，节省了大量的曝光时间。

A new method of making synthetic dynamic hologram by dividing vertical viewfield is analysed theoretically and experimentally herein. Dividing the main hologram H 1 vertically into hologgraphic units, in each unit one of series of 2 dimentional photographs which are the images of the objects continuous changement is recorded. With this H 1 an image hologram, a synthetic dynamic hologram, can be obtained. Due to H 1 can be recorded with silver halide plate in this method, a great deal explosure time is saved.
