本文首先对数字全息技术的记录和再现的基本原理、数值重建算法、频谱滤波方法，数字全息图的记录条件、再现光场的分离条件等基本问题进行了分析讨论-Firstly, the basic principle of the recording and reproducing of the digital holography, numerical reconstruction algorithm, the spectral filtering method, the digital hologram rec

实现离轴变换再现算法！离轴全息再现有零级像干扰，高通滤波，滤掉不必要的成分，对离轴全息图进行FFT，等到全息图的频谱分布- Off-axis transformation algorithm to achieve reproduction! Off-axis holographic reproduction zero level as interference, high pass filter, filter out unwanted ingredients, off-axis holog

这是关于二维全息的GS算法，可以插入图片生成全息图和再现像(This is a GS algorithm for two-dimensional holography, which can be inserted into a picture to generate a hologram and a reproducing image.)

这是产生二维全息图和再现像的GS算法，可以插入任意图片生成。(This is a GS algorithm for two-dimensional holography, which can be inserted into a picture to generate a hologram and a reproducing image.)
