摘要: 以优化系统整体性能为目的，针对弹载跟踪系统，设计了一种基于共形光学整流罩的红外光学系统。首先，根据载弹信息，通过数值仿真计算及相关验证风洞试验，得到共形整流罩外曲线；通过优化分析，得到整流罩内曲线。应用Wassermann-wolf方程，结合Zernike多项式像差分析方法，设计两片固定式校正片，用于校正共形整流罩带来的附加像差。选择F=2的制冷型中波红外探测器，设计折反式成像光学系统，通过ZEMAX软件优化共形光学整体系统，并进行了公差分析。共形光学系统焦距120 mm，冷阑效率100%，设计传函在各视场范围内均大于0.6，公差分析后，均大于0.4。通过成像测试试验，结果表明，共形光学系统成像质量良好，满足跟踪设备对光学成像系统的要求。

Abstract: In order to optimize the system's total performance, aiming at missile tracking system, a kind of infrared optical system with the principle of conformal optics was designed in this paper. Firstly, according to the missile's flying information, through numerical simulation computation and relative wind tunnel experiments, the outer figure of the conformal dome was gotten. By optimizing the optical path differences, the inside figure of the conformal dome was obtained. By using the Wassermann-wolf equations and the Zernike aberration analyzing method, the fixed two pieces correctors were designed for correcting the aberration induced by conformal dome. The detector used in this system was a F=2 mid-wave infrared detector made by Sofradir in France. The imaging optical system was designed in refraction/reflect structure, then by using software ZEMAX the final system was gotten. Finally, the tolerance analysis was done. The focal length of this conformal optical system was 120 mm, the cold diaphragm efficiency was 100%, the MTF(modulation transfer function) of all fields are all above 0.6. Even after the tolerance analysis, the MFT value was also above 0.4 which is good enough for manufacture. The results of imaging tests show that this kind of conformal optical system is good in imaging.
