摘要
为了方便快速地计算像差,采用MATLAB中GUI工具,从球面光路计算的向量公式出发,得到了一计算像差的程序界面,在程序界面输入各个相关参量,点击界面上各种像差菜单就能得到不同视场角在光瞳上不同入射点的各种像差,并可以计算系统的焦距和理想像面的像距以及给出像面的模糊程度(同一物点发出的不同方向光线的聚焦程度的具体数值。结果表明,该软件程序语言简单,程序语句大大减少,占用机时少,运行结果正确。程序通过编译后可以脱离MATLAB运行环境独立运行。
In order to calculate aberrations rapidly and easily, MATLAB＇ s GUI tools are used to make a program interface. A user interface software for calculating light aberrations is realized according to vector formulae to trace optical path passing through spherical faces, when various parameters are input in the program interface, different kinds of aberrations with different view-field angles and different incident points on the pupil can be got by clicking aberration menus, containing on-axis aberrations, off-axis aberrations of wide beam in the tangential plane and the sagittal plane, and aberrations of sharp beam. The focal distance, the ideal image distance of an optical system and spatial ambiguities in images are also obtained. It can be used as a single interface to calculate all sorts of aberrations. The soft has a simple programming language, fewer programming sentences, less machine time and correct running results. The compiled program can be run independently on any operating system without the MATLAB operating environment.
