In this paper, the design of kinoforms in double-random-phase encryption method is optimized by the memory-based simulated annealing technique, which is applied to the simulation experiment of a binary image and an image with gray levels. 采用基于记忆的模拟退火法对双随机相位加密中的相息图进行优化设计,并用该法分别对一个二元图像和一个灰度图像进行了模拟实验。
The kinoforms of cylinderical lens and cone lens are calculated based on the preparation principle of computer generated holographic lens. 本文基于新近提出的计算全息透镜制备原理,对柱面透镜和圆锥透镜的相息图作了计算。
