摘要

摘要: 对双波段红外扫描成像光学系统进行了研究，结合三次成像技术和100%冷光栏效率技术，设计了一个共口径双通道红外扫描成像光学系统。该系统包括前端共用的双反射系统、分束镜、准直镜组、扫描镜和成像镜组。光波经过双反射系统在主镜之后被分束镜分成中波红外通道（3 m～5 m）和长波红外通道（10 m～12 m），经准直镜组及成像镜组会聚探测器上，实现中波红外系统与长波红外系统共口径同步成像。设计结果表明，长波红外系统传递函数在18 lp/mm处达到0.4以上，中波红外系统传递函数在18 lp/mm处达到0.78以上，满足实际应用的要求。

Abstract: A scanning imaging optical system of dual infrared spectrum is studied, and combined with the triple imaging technology and 100% cold shield efficiency technology, a common-aperture dual-channel infrared scanning imaging optical system was designed. The system was composed of a common twomirror system, a beamsplitter, a collimation system, a scanning mirror and an imaging system. Light was divided into the mid-wavelength infrared (MWIR,3 m～5 m) waveband and the long-wavelength infrared (LWIR, 10 m～12 m) waveband by the beamsplitter, then they were converged on the two detectors through the collimation system and imaging system, and the MWIR and LWIR optical systems realized common-aperture synchronization imaging. The use of small scanning mirror greatly reduced the scanning mirror-s difficulty of manufacture and test, the difficulty of designing the control mechanism, and reduced the system size and weight. The result shows that the LWIR system transfer function is above 0.4 at 18 lp/mm, and the MWIR transfer function is above 0.78 at 18 lp/mm, which satisfies the needs of practical applications.
