Design of a 3.7~4.8 μm Catadioptric Secondary Imaging MWIR Optical System

  • 摘要: 为满足小、远目标和空间目标的光学特性测量需求,提出以RC结构为设计基础,通过曲线方程和高斯公式确立反射式光学系统初始结构参数。为达到优化设计目的,结构中引入了二次成像中继镜组,解决了100%冷光阑效率问题。通过ZEMAX建立评价函数,仿真测试表明:设计完成的红外二次成像折反射式光学系统口径200 mm,焦距380 mm,结构紧凑简单,成像质量满足实际测量需求。
    Abstract: The system is based on an RC structure to measure the optical characteristics of small targets and space targets. The initial structure of the reflective optical system was established by calculating the curve equation and the Gaussian formula. The re-imaging relay lens group was introduced into the structure of the system to realize the optimal design, which solves the problem of 100% cold diaphragm efficiency. The imaging quality was evaluated using Zemax, and a system with a focal length of 380 mm and a diameter of 200 mm is not only compact and simple, it also meets the actual measurement requirements.
