摘要 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。 The digital holography image processing is used to delete the zero order and integration images, a Laplacian transformation and an convolution are used to improved the original image. A detailed description of the reconstruction procedure and the experimental result are given.
