摘要
研制了一套基于热光阑的大F数制冷型红外光学系统,通过优化热光阑的设计参数,消除了热光阑自身辐射、外界环境杂散辐射及冷反射对系统性能的影响,很好地满足了热成像性能高、长焦距、体积紧凑等设计需求。性能测试及成像效果表明,通过合理的优化设计,反射热光阑不会给系统的性能带来明显的变化,验证了热光阑设计方法的正确性与可行性。
Abstract
A large F/number (F/#) cooled infrared optical system based on warm diaphragm was designed.The influences of thermal radiation of the warm diaphragm itself,the external environment stray radiation and the narcissus reflection on the system performance were eliminated by optimizing the design parameters of the warm diaphragm.The system achieved the design requirements of high thermal imaging performance,long focal length and small volume.Performance tests and imaging results show that:the reflective warm diaphragm will not bring significant change to the performance of the system through reasonable optimization design,which verifies the correctness and feasibility of the design method.
