摘要
提出了迭代傅里叶变换算法设计二元计算全息图的新方法。采用迭代傅里叶变换算法，计算配置与目标物相关的迭代位相，使物波频谱具有有限带宽和平滑性。实验结果表明，迭代傅里叶算法可求得适当的位相参数，使计算全息图再现象上的斑纹被明显抑制，提高了信噪比和衍射效率。
A method for implementing image compression in video telephone by using digital signal processing is presented in the paper.The key technology of the method is deeply described.The improving prospect for the video telephone has been predicated.
