部分相干光学成像系统的光学传递函数和像质评价准则

根据光学成像理论，建立了部分相干成像光学系统的光学传递函数。该函数与非相干成像光学系统传递函数相同，因而部分相干成像和非相干成像两者的光学系统波面像差公差标准也是相同的。这一点解释了显微镜光学系统的光学设计惯用法则：镜头像差公差标准的选择，并不因为采用成像照明方式的不同而有所差异。

Optical Transfer Function and Image Evaluation Criterion of an Optical System with Partially Coherent Illumination

The optical transfer function (OTF) of an optical system with partially coherent illumination was developed according to the theory of image formation. This function is the same as the incoherent OTF of optical system. So the permissible tolerances of the wave aberrations of optical system are identical for illumination either incoherent or partially coherent. This conclusion explained the customary rule of optical system design of microscope that the tolerances of wave aberrations are the same for both the incoherent and partially coherent illumination, no difference for various forms of illumination.
