摘要
为了使一种全新的离轴四反射式光学系统达到很好的光学性能,对在该光学系统中的四个大小形状不一的球面反射镜分别进行了分析。结合反射镜的结构形状和相对位置特点找出了最适合每片反射镜的支撑方案。经过有限元分析进行了辅助设计和优化设计,使各个支撑结构达到了性能最佳、整机重量最轻、公差分配最合理。
For the good performance of a new four-mirror reflective anastigmat optic system,the spherical surface mirrors which are different from each other in this optic system are analyzed. To fit supporting structure for every mirror is found out by considering the shape and characteristic of position of mirrors. By the assistant of finite element analysis,it meets the demand of the supporting structure performance good,the weight is light,the tolerance distribution is reasonable.
