Optical design of off-axis three-mirror system for infrared dual-band scene simulator

  • 摘要: 针对红外双波段成像系统性能测试与评估的应用需求,设计了3 m~5 m和8 m~12 m红外双波段视景仿真用离轴三反光学系统。在共轴三反光学系统成像理论基础上,分析了孔径光栏远离主镜的离轴三反系统像差特性,研究了大出瞳距、大相对孔径条件下离轴三反光学系统的结构设计和像差平衡方法。系统焦距为330 mm,F#为3,视场为64.5,出瞳距为750 mm,在空间频率10 lp/mm 处,中波红外MTF0.65,长波红外MTF0.4,接近衍射极限。具有大视场、大出瞳距、高分辨率、结构紧凑等特点。
    Abstract: To meet the requirements of infrared dual-band imaging system performance testing and evaluation applications, an off-axis three-mirror system operating at 3m ~ 5m and 8m ~ 12m band was designed for infrared dual-band scene simulator. The aberration characteristics of off-axis three-mirror system with aperture departing far from the primary mirror were analyzed based on the coaxial three-mirror imaging theory, the design methods of the optical structure and aberration balance of the off-axis three-mirror with large eye relief and large relative aperture were discussed. The focal length of the system is 255 mm with F# 3, the field of view is 6 4.5 , the eye relief is 750 mm, the image quality of the system approaches the diffraction limit with MTF0.65 for long-wave infrared band and MTF 0.4 for mid-wave infrared band at 10lp/mm spatial frequency. The system is characterized by large field of view, large eye relief, high resolution and compact structure.
