光学传递函数的计算,无论是几何的还是物理的,通常都是在7Q16或719机等中型以上的计算机上进行的。而象BX-1这样的小型机,由于其内存小,计算速度慢,因此很难进行这一类计算。本文介绍了一个在BX-1机上运行的大容量程序,该程序具有计算光学系统波差、波色差、二维渐晕、点列图和几何光学传递函数等十二个功能。对于在BX-1机上运行大容量程序时所经常遇到的计算机內存小、运行速度慢等问題也作了一些讨论。
The calculation of optical transfer functions, whether geometric or physical, is usually performed on a computer of medium size, such as a 7Q16 or 719 machine. And minicomputers such as BX-1, because of its small memory, slow calculation, it is difficult to perform this type of calculation. This article presents a high-volume program running on a BX-1 machine that has twelve functions for calculating optical system wave aberration, wave color aberration, two-dimensional vignetting, point column and geometric optical transfer functions. There are also some discussions on the issues such as small computer memory and slow operating speed that are often encountered when running large-capacity programs on the BX-1.
