计算全息图的基本理论与制作

与传统光学全息相比,计算全息图因具有极高灵活性,制作简单并且能够记录实际不存在物体的特点而被广泛应用。越来越多的专家和学者致力于研究计算全息图。在介绍计算全息基本理论后,采用四阶迂回相位编码方法,基于MatLab平台分别制作了傅里叶二元计算全息图和菲涅耳二元计算全息图。再现实验中得到的再现像直观明显,对研究和开拓计算全息图更广泛的应用具有参考价值。

Basic theory and realization of computer generated hologram

Compared with traditional optical holography,CGH has been widely used due to its high flexibility,simple realization and the capability to record inexistent object.More and more experts and scholars have dedicated themselves to the research of CGH.After a brief introduction of the basic theory of CGH a fourth-order detour phase encoding method is used to obtain Fourier binary CGH and Fresnel binary CGH based on MatLab.The reconstruction images are explicit and clear in the reconstruction experiment.It′s a good reference for research and development of extensive applications of CGH.
