透镜系统的镜面反射杂光的计算——鬼像的模拟与分析

Calculation of Veiling Glare Due to Reflections Between Surfaces——Ghost Image Simulation and Analysis

杂光是影响光学系统像质的重要因素之一。本文提出了一种计算透镜面反射杂光的方法:近轴近似法与有限光线追迹法的混合应用。介绍了鬼像的模拟与分析软件的功能及结构。最后以实例说明。

Veiling glare is one of the important factors causing deterio- ration of image quality in optical systems. A new method, using the paraxial approximation and the finited ray tracing, is proposed in calculating veling glare due to reflections from com- ponent surfaces. The function and structure of the software for the ghost image simulation and analysis are outlined. A real optical system was analysed as an example.
