针对单星模拟器主体光管中存在大量杂散光的问题,本文提出设置多级拦光光阑消除杂散光。该方法根据多级拦光光阑的设计原则设定光阑的位置和孔径,采用TracePro软件对设计结果进行了模拟分析。实验结果表明,杂散光得到了有效的抑制,保证了单星模拟器的模拟星光平行度2″的指标。
Aiming at the problem of a large amount of stray light in the light pipe of the single-star simulator, this paper proposes setting up a multi-stage stop light diaphragm to eliminate stray light. The method sets the aperture position and aperture according to the design principles of multi-stop light diaphragm, and uses TracePro software to simulate the design results. The experimental results show that the stray light is effectively suppressed, which ensures that the single-satellite simulator simulates the parallelism of 2 ".
