像差计算的可视化应用软件开发

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。

Visualization application software development for calculating light aberrations

An applied program interface for calculating light aberrations is presented based on vector formulae used to trace optical path passing through spherical faces. When various parameters, including the curvature radius of all mirror surfaces r, the refractive index n, the distance d between two mirror surfaces, the beam aperture hmax, the pupil position Lz, the height of object Ymax, the distance of object L and the maximum angle of half field of view and so on, are inputted in the program interface, we can get different kinds of aberrations of light with different view-field angles and different incident points on the pupil by knocking 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. We also obtain the focal distance, the ideal image distance of an optical system and spatial ambiguities in images. Put it at an interface to calculate all sorts of aberrations.
