摘　　要：首先获取三维物体不同视角的透视图,并对这些视图上的不同单元的光强信息用计算机分别收集、编码,得到一组编码片,依次在同一张全息片的不同点区域上记录编码片的信息。当普通灯光照明全息片时,双眼能同时分别接收到反映物体两个侧面的清晰再现像,构成体视像,而且该像会随着人眼的移动而产生动感效应。本方法的优点是利用计算机对信息处理的精确性,再结合全息记录、再现的准确性,制作了一张点阵合成动感全息图样品,能看见清晰立体再现像,观察方便,人眼移动时再现像的动态效果逼真。Firstly some perspective picture viewed from different angles must be obtained. The intensity distribution of light of different parts of the pictures are collected and encoded with a computer. A series of encoded films are obtained. If the intensity information of each film is recorded successively on the different dot region of one holographic film, two clear reconstructed images can be displayed respectively in each eye as the holographic film is illuminated by a common lamp, each image shows the different two - dimensional information of the object, so the stereoscopic image occurs. When eyes change the position the image will move and change. The merit of this method is that the accuracy of the computer processing the information combines the exactitude of the holograph recording and reconstruction. A clear stereoscopic image can be easy to observe from the sample film. As eyes move, the image has been displayed vividly.
