摘要
从衍射理论出发研究了平面光波和高斯光波通过光学系统孔径的聚焦特性，对其轴上点强度分布和焦面强度分布进行了定量比较。最后，用斯特列尔比对像差光学系统的聚焦特性进行了评价。
The focusing characteristics of a uniform and a Gaussian beam when passing through theaperture of an optical system are investigated by means of the diffraction theory.The quanti-tative results of comparisons of axial irradiance and focal-plane distribution between the twobeams are given. The focusing characteristic of an aberrated optical system in terms of Strehl ratio is assessed.
