根据数字全息的可计算特性 ,提出用图像处理的方法直接对数字全息图在空域进行预处理 ,使其再现时不出现直透光和共轭像 ,大幅度提高再现像的质量。并进行了实验验证
According to the computable characteristic of digital holography, the method of image processing is proposed to preprocess the digital hologram directly in the spatial domain so that the direct hologram and the conjugate image do not appear when reproducing, thus greatly improving the quality of the reproduced image. And experimental verification
