本文陈述一个光学系统CAD软件包所具有的功能和特点,这些特点主要是所采用的计算方法不同于国内外同类的软件包。
The Optical System CAD Software Package is discribed which is different from similer in China and in the world in mathematical computation methods. The soft- ware package provides a good tool for automatic or semi-automatic design zooms and lenses. The optical systems can be spheric surface systems and the aspheric systems and it can be or not be central obstruction one. All of parameters of lenses can be automatically changed during aberrations to be automatically corrected and the convergence speed of autodesign is rather quick . For evaluating the optical system, the software package can calculate the classical geometric oberrations, the spot diagrams, the energy distrubition curves, the point spread functions, the wave Optical Transfer Functions and the geometric OTF. The new wave OTF formula [l] is used and the new G-OTF formula [3] is given on the axis , using Bessel function of order zero. Newton method and the least square method are used for computing Gauss optics parameters. Focuses and initiate distances of group elements are inverse calculated from a initiate structure of the zoom lens so that multiple variatious of focus can be satisfied . In fact, this is to do autodesign for Gauss optics parameters of zoom lens. And then, it can display and draw all of the above curve pictures. It also has many functions for artificially interfering automatic design process and for bring the initiative of the designer into full play. During past 20 years, the set of programme has been used to design and produce a variety of more than 40 lens systems,including for movies and television cameras,photography cameras, projectors, epidiascapes, developing and printing, recording, monitoring, information processing , infra rad image and many zoom lenses. This software package is awarded with the third rank prize of Sciences and Technology Progress by the Chinese A-cademy of Sciences.
