摘要

摘要: 针对空间成像光学系统的像质容易受到瞬时视场外杂散辐射的影响，利用杂散光分析软件建立一个共形光学系统光学机械结构模型，并对其进行反向光线追迹，从而确定出该系统中对瞬时视场外杂散辐射光的聚集贡献较大的关键表面及视场外杂散辐射光的主要传递路径。采用在系统中加入多级挡光环辅助结构的方式获得了100%的瞬时视场外杂散光屏蔽效果。该设计方案具有简单易行的特点。

Abstract: The imaging quality can be easily degraded by stray light in some space imaging optical systems, so measures are taken to handle it. An optomechanical model of conformal optical system was established in stray light analysis software. And we tried to find out the systems critical surfaces in collecting out of field stray light by backwards ray tracing method. There were three baffles used in this system to block stray lights, and the simulation result proved the blocking effect of the baffles.
