| 摘 要： | 介绍了计算全息干涉图制作的基本原理，并根据实现原理设计相应的计算机仿真算法实现各类波面计算全息干涉图绘制。算法主要基于牛顿迭代法思想。在全息图面上搜索满足二元全息函数基本方程的点以获取干涉条纹的具体坐标位置，并将它们连成线或者绘制与y轴平行小线段构成计算全息干涉图。给出了MATLAB平台上球面波、锥面波及螺旋形波面的计算全息干涉图。该算法提供了制作计算全息干涉图的新手段，同时仿真结果也表明这是一种高效快捷的实现方法。

| Abstract: | According to the basic principle of holographic interference, a new method has been proposed for the implementation of interference type holograms with computer simulation. The main idea of the algorithm is based on the Newton iteration. By searching all the points which fit the binary holographic equation throughout the whole hologram and then connecting them up or plotting line segment parallel to y axis, the interference type Computer-generated Holograms of different patterns are given, such as the waves of sphere, pyramidal and helicoids. MATLAB is used as implementing method. The simulation result demonstrates that this is an effective way for the realization of interference type Computer-generated Hologram. |
