摘要

在此基础上，我们提出了一类具有点扩展函数(PSF)或线扩展函数(LSF)非负性的消瞳必要函数，并研究了一类具有PSF或LSF在最大值两侧非负性单调减小的消瞳必要函数。PSF或LSF的这种行为使得可以抑制扩展对象边缘的图像中的振荡，但它增加了图像边缘的移位和扩展，因为这些现象是相互补充的。

Apodization in coherent image formation

A class of the apodizating pupil neccessary functions (PF)s which affords non-negativity of the point spread function (PSF) or the line-spread function (LSF) has been proposed previously, and we also examine a class of the PFs which affords non-negativity and monotonic decrease of the PSF or LSF on both sides of the maximum. Such a behavior of the PSF or LSF makes it possible to suppress oscillations in the image of the extended object edge, but it increases the shift and spreading of the image edge, because these phenomena are mutually complementary.
