摘　　要：分析了离轴三反射镜系统成像特性.根据共轴三反射镜光学系统像差理论,确定结构参数的基本计算公式.设计了长焦宽视场的离轴三反射镜光学系统,分析了系统结构参量对像差的影响.结果表明,该系统视角较大,地面复益范围较宽,成像质量接近衍射极限.In order to minimize the effect of central obstruction on the image quality of reflecting optical system, the off-axis three-mirror reflective system plays an important role in application and research. The advantage of the off-axis three-mirror reflective optical system is analyzed, the calculation method of the structural parameters of co-axial three-mirror reflective optical system is described. A system with large field-of-view and long focal length is proposed. The results show that the system has good image quality.
