大口径折反射式光学系统在空间遥感仪器中广泛应用，反射镜的支撑结构直接关系镜面面形变化从而影响光学遥感器的成像质量．建立了光学系统的光机结合分析方法，使得在设计阶段就能评测光学元件支撑结构是否满足要求，得到支撑结构对成像质量的影响的直观结果．这一方法也可用于光学系统的光机热结合分析．

The reflection optics with large aperture is widely used in spatial remote instruments. The imaging quality of the optics is closely related to the mirror surface deformation which caused by the mirror's supporting structure. An interface program between the mechanical finite element analysis and the optic design software is presented. In this way,it can directly study the deterioration of the optics imaging quality which caused by the supporting structure. During the design of the optical system,this method can also be used in integrated analysis of optics,mechanics and thermodynamics.
