本文提出了一种基于散焦调制处理的图像复原方法，假定相干成像系统中存在球差的弱散射目标。目前的分析表明，如果在图像积分中使用作为散焦值的函数的适当的双极(正和负)加权函数，则可以通过对散焦系列应用图像积分来完全校正球差的影响
This paper describes an image restoration method based on defocus modulation processing, assuming weakly scattered objects in the coherent imaging system involving spherical aberration. The present analysis shows that the effect of the spherical aberration can be completely corrected by the image integration applied to the defocus series, if appropriate bipolar (positive and negative) weighting functions as a function of the defocus value are used in the image integration
