本文叙述了在微型计算机中以BASIC语言编制的光学系统计算程序所出现的若干问题及其解决办法。介绍了一个由ALGOL语言移植过来的球面光学系统的BASIC语言的通用计算程序。该程序可进行照相、显微、望远及折反射等光学系统的计算,具备焦距缩放,ΣS_Ⅳ不变、象平面位移后计算实际象差等功能。並例举了采用此程序为激光电视录放装置所设计的物镜的象差数据。最后叙述了在微型机上进行光学设计的优点。结果表明:在微型机上采用此程序进行光学设计是成功而又方便的。
This article describes some problems that arise in the calculation of optical systems in BASIC languages and their solutions in microcomputers. A general calculation program of BASIC language of spherical optical system transplanted by ALGOL language is introduced. The program can be photography, microscopy, telescope and catadioptric optical systems such as the calculation, with focal length scaling, ΣS_IV unchanged, as calculated after the plane displacement aberration and other functions. An example of the aberration data of the objective lens designed for the laser TV recording / reproducing apparatus is given. Finally, it describes the advantages of optical design in microcomputers. The results show that it is a success and convenience to use this program for optical design in microcomputers.
