摘要 为系统地介绍面向航天快速发射的微纳卫星光学载荷设计与制造过程,从光学原理设计出发,以折反式光学相机为研究对象,主要介绍光学元件的结构设计、力学分析、加工及检测过程,最终得到500 km对地极限分辨率为3.1 m的光学载荷。研制结果表明,通过合理的光机结构设计,并选取单点金刚石车削、磁流变修形以及计算机控制光学表面成形加工等工艺,能够满足航天快发技术对于光学卫星载荷短研制周期、高性能、轻质量、小体积以及低成本的技术要求,为研制同类型相机和进一步提高航天快发技术提供了参考。 This study focuses on the design and fabrication of a catadioptric optical camera used in rapidlaunch aerospace systems.We first introduce the optical design principles followed by the structural de⁃sign,mechanical analysis,processing,and inspection process of the optical components.Finally,an opti⁃cal payload with a resolution of 3.1 m to 500 km is obtained.The results show that the follow-up develop⁃ment process can be greatly simplified through reasonable optical principles and opto-mechanical structural design.Optical components that meet the accuracy requirements can be quickly processed using singlepoint diamond turning(SPDT),magneto-rheological finishing(MRF),and computer-controlled optical surfacing(CCOS).The above methods can fulfil the technical requirements of rapid-launch aerospace technology for optical satellite payloads;the methods are quick,highly efficient,lightweight,and econom⁃ical.This article provides a reference for the development of the same type of camera and the improvement of rapid-launch aerospace technology.
