摘　　要：三维技术已经越来越广泛地应用于计算机图像学中。近年来,全息又成为制作高质量3D图像最为普遍的方法。文中主要讲述了光全息的有关知识,并讨论了基于干涉全息图的计算方法。以点光源的计算全息方法为例,利用计算机模拟光干涉,并计算出各点光的相位,生成了基于干涉的点光源的全息图。3D displays has been used and applied widely into computer graphics. Recently, holography has become the most popular method for rendering high quality 3D graphics. This paper addressed the fundamental knowledge about optical holography, and covers the method of computing holography based on optical intederence, It puts the hologram computation of a point source as example. A computer generated holographic image is computed by numerically simulating the physical phenomena of light interference. It is possible for a computer software to calculate the phase of light of an object. Also it implemented a computer program that is able to generate hologram by computing the phase of a point light source.
