摘　　要：以初级像差理论为基础,重点分析了离轴三反系统初始结构参量的确定方法。利用CODEV软件编译计算并生成离轴三反光学系统初始结构的人机交互程序。将红外双色复合成像和离轴全反射系统结合起来,设计了一种共孔径红外双色离轴全反射系统。该系统具有长焦距、大孔径、宽波段、平像场等特点,结构简单,像质优良,在航空航天领域具有广泛的应用前景。Based on three-order aberration theory,the method for determining the initial structural parameters of off-axis three-mirror optical system was analyzed in detail.A human-computer interaction program for generating the initial structure of off-axis three-mirror system was compiled by using CODEV software.An off-axis total reflection optical system for common aperture IR dual-color imaging was designed.The characteristics of this system such as long focal length,large aperture,avoided curvature,wide spectrum,simple structure and high image quality could satisfy the requirements of remote sensing,space photography,infrared multispectral detection and other applications in the field of aeronautics and astronautics.
