摘要
本文在计算机制全息图的理论基础上 ,以点光源菲涅耳全息图为例提出利用微小变量法来计算物点与全息图样点之间的距离 ,从而加快了计算输出全息图的速度。
Based on the theory of computer_generated hologram, small variation method has been proposed for computing the distanse between the object point and the position on hologram taken Fresnel's point light CGH as example. So the fast algorithm for Fresnel hologram has been offered. This laies the foundation of fast computating way for an actual object's hologram.
