摘要
分离式终端光学系统(FOA)的光学元件多,输出能量高,鬼像分布复杂,给FOA的鬼像分析带来很大的挑战。利用Zemax结合自主研发软件Ghost对分离式FOA的鬼像分布进行优化设计,建立针对真空窗口和屏蔽片的角度及其与聚焦透镜的间距对FOA中鬼像分布影响的分析模型,经仿真计算得到两种适合于分离式FOA的鬼像分布方案,对比其优缺点,最终确定合理的分离式FOA鬼像分布设计方案。
The separated final optics assembly(FOA) with high power has too many optical elements and complicated ghost distribution,which cause difficulty in ghost analysis of FOA. By using the Zemax software and Ghost software designed by ourselves, we analyze the ghost distribution of the FOA, establish the model to analyze the effects of the angle between the vacuum window and debris shield and the distance from the focusing lens to vacuum window or debris shield on the ghost distribution, use the model to analyze two ghost distribution schemes for the separated FOA, contrast the two designs, and get the final ghost distribution of the separated FOA.
