| 摘 要： | 本文讨论线扩散函数和两边梯度的一般公式和规化因子线扩散函数和两边梯度间的关系。并给出以波差方差的函数Ω所表征的近似方程,并研究了在对称光瞳和旋转对称光学系统的情况下,特别是当圆形光瞳时,波差系数和Ω的偶部ΩE和奇部Ω0之间的关系,并利用ΩE来确定最佳焦面的位置和利用Ω来求得线扩散函数最大值的位置,同时给出了一些情况象差公差的实例。

| Abstract: | This paper disccuses the general formulae and normalisation factor of line spread function and the edge. An appsoximation equation specified by Ω, which is a function of the wavefront variation,of the Strehl ratio of the LSF, is given. The relationship between wavefront coefficients and Ω which is divided info even part ΩE and odd part Ω0 for the symmetrical aperture and for rotational symmetrical optical system, especielly for circular aperture, is investigated. Then use of ΩE to determine the best focal plane and Ω0 to get the position of the maximum value of LSF is described. Finally some examples about the aberration tolerances in some cases are showen. |
