摘要
采用基于蒙特卡罗法自行编制的杂散辐射计算软件HITSLT-1,模拟了空间红外光学系统的杂散辐射。从系统温度、镜筒物性、视场光阑物性等角度分析了其对于到达红外多光谱测量仪焦平面杂散辐射的影响,为红外光学系统的设计与杂散辐射抑制提供了参考依据。
With the help of stray radiation calculating software HITSLT-1, which based on the Monte Carlo Method and programmed by HIT, the stray radiation in a space infrared optical system is stimulated. From the points of system temperature、physical character of the drawtube and diaphragm, their effects to the stray radiation reaching to the focus plane are analyzed, which provides references and suggestions to the thermal control and design of the optical system.
