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。 The method of making the dynamic hologram by using the vertical field of view splitting method is theoretically and experimentally analyzed. The master hologram H1 in the two-step rainbow holography is divided into a number of holographic units. In each unit, a series of two-dimensional images of the objects in a series of continuously changing states are recorded, and an image hologram H2 is produced by using the master hologram to obtain a composite Dynamic hologram. This method records the master hologram H1 with a dry version of silver salt, saving a lot of exposure time.
