光学系统照度分布及软件

Optical System Illumination Software

对照度计算的常用方法进行了比较,编制了通用的照度计算程序,可计算平面、球面、二次曲面、高次轴对称曲面等系统的照度,考虑了透镜的反射和吸收、中心遮栏、镜面镀膜、光源的光谱分布等情况,提出并讨论了照度计算在色度方面的应用。

The methods of illuminance calculation of optical system are systematically analysed in this paper and a valuable program are presented. The program could be used to calculate the illuminance of such systems as plane , sphere,2-D curved surface,multi-D axisymmtric curved surface and so on. The lens reflection and absorption,central shade,lense coating,spectrum distribution of light source are all considered in the program. In addition,the utility of illuminance algorithm in the field of chromaticity is put forward and discussed.
