| 摘 要： | 本文研究了光学傅氏变换的离焦近似问题,导出了使傅氏变换关系近似成立在光学上所需要满足的离焦条件,并以此为基础,提出用离焦谱平面方法对电子显微照相图象进行解卷积处理,使得光学解卷过程大大简化。实验得到了满意的结果。

| Abstract: | In this paper, the approximation of optical Fourier transform in the cases of defocus is studied, and the relation of condition required for the defocus approximation of Fourier transform is derived. From this principle a method of using the defocus approximation is described for deblurring an electronic micrographic image, which makes the optical deconvolution process significantly simplified. The experimental results show that the quality of the image of an amorphous carbonic film is notably improved. |
