摘要
采用光学系统公差的非线性模型,以波差方差或几何传递函数为评价函数,据此编制的程序可进行光学系统公差的优化设计和统计分析。此外,程序还可进行光学点图计算,显示出在人工给定离焦面上点分布,给出空间光线对主光线的能量集中度曲线和OPD均方根值。
Adopting a nonlinear model of the optical system tolerance and regarding wave-Variance or Geometrical OTF as evaluation function of the system, this program can be used to design and analyse the tolerance of the optical lens system. Besides, it can also be used to calculate Spot-Digram of the system so as to display ray distribution in the defocussed image plane, give out the curve of the ray's energy density and Square-root-means of its OPD value in that plane.
