提出一种动态数字彩虹全息显示术,该技术将计算机制全息术和动态双视彩虹全息合成术相结合,根据彩虹全息的基元全息图为“线全息图”以及双眼立体视觉的特点,计算物点的线全息图上两个片断,使得两个全息图片断分别对应左右眼视图,同时对彩虹全息图的狭缝像进行横向分割,使得不同区域成为物体不同姿态的视窗,从而达到动态显示的效果。给出了数字动态全息的计算方法,并得到了初步的实验结果。
A technique called computer-generated dynamic rainbow hologram,which combines computergenerated hologram and synthetic technique for double-view dynamic rainbow hologram is presented. According to the characteristic of that rainbow hologram's elementary hologram is "line-element hologram" and the binocular stereo vision, it computes two slices from the "line-element hologram. And right and left eye views are made respectively corresponding to the two slices. The rainbow hologram's slot image was divided simultaneously. The aim of dynamic display can be realized if the region of the slot image corresponds to the object's different gesture. The new method was applied,and the elementary experiment result is given.
