| 摘 要： | 光学系统的杂散光极易在系统内形成多个鬼像,这不仅严重影响光束质量和传输特性,并可能对系统光学元件造成永久性损伤。该文提出了一种基于光线追迹的分析光学系统杂光影响的有效方法,建立适合各类光学系统杂散光及鬼像分析的数理模型。编制了专门的杂散光分析软件,通过计算机光路模拟,对光学系统中的鬼光束进行全面、系统分析,可得出系统鬼像及关键元件处的能量密度,从而在光学系统设计阶段排除鬼像的潜在危害。

| Abstract: | Stray light generated in optical system form s a lot of ghost images,which not only seriously influence the beam quality and propagation properties,but also damage optical components.Based on the basic principle of geometrical optics,the transmission of beam is analyzed,a ray tracing method of ghost analysis is mentioned,the mathematical and physical model for analysis of stray light and ghost images is set up,the analysis software is presented.Taken a simple facility as example,these ghost images and the energy density of key components are gotten correctly.Various kinds of protective measures about the component damages are discussed and assessed.The results are instructive to the actual work. |
