摘　　要：对采用制冷型中波红外探测器的光学系统,设计了一个多光谱中波红外汇聚系统,针对分色滤光片引入外界杂散辐射的问题,设计了一个热辐射抑制光阑,对其形状及位置不断地迭代优化,达到抑制系统外界杂散辐射的目的。经TracePro仿真验证表明,运用此热辐射抑制光阑后,总的杂散辐射降为之前总杂散辐射的8.8%,对改善成像质量有明显的效果。For the optical system using refrigeration mid-wave infrared detector,a multi-spectral mid-wave infrared convergence system is designed.To solve the problem of external stray radiation introduced by color separation filter,a thermal radiation suppression stop is designed,and its shape and position are optimized through iteration,so as to suppress the external stray radiation of the system.The TracePro simulation shows that this thermal radiation suppression stop can reduce the total stray radiation to 8.8%.It has obvious effects of improving the imaging quality.
