摘　　要：随着我国航天事业的持续发展和不断进步,航天光学相机正在朝着大口径、大视场、高分辨、轻量化的趋势发展,这对相机的设计分析提出了更高的要求。光学系统焦距与光学口径不断增加,光机系统刚度受质量限制提升空间有限,其对星上活动部件在轨正常工作所引起的微振动也越来越敏感。航天光学相机的微振动对其在轨成像质量会造成影响。因此,近年来卫星微振动及其控制问题越来越受到关注。通过对国内外航天光学相机的光机集成分析方法的论述与分析,探讨了目前光机集成分析的关键技术与发展方向。针对目前国内光机集成分析其存在的局限,提出了建立微振动传递全链路数学模型进而构建航天光学相机微振动像质退化机理的设想。With the continuous development and progress of China’s aerospace industry,aerospace opti⁃cal cameras are becoming more lightweight with large apertures,large fields of view,and high resolution,which results in higher requirements for their design and analysis.The focal length and optical aperture of optical systems continue to increase,whereas the stiffness of optical mechanical systems is limited by mass.They are also increasingly sensitive to micro-vibrations caused by the normal operation of moving satellite parts in orbit.The micro-vibration of space optical cameras affects their imaging quality in orbit.Therefore,in recent years,satellite micro vibration and its control have attracted increasing attention.Based on discussions and analyses of the optical mechanical integration analysis methods of aerospace opti⁃cal cameras at home and abroad,the key technologies and development directions of optical mechanical in⁃tegration analysis are discussed.In view of the limitations of optical mechanical integration analysis in Chi⁃na,this study proposes the idea of establishing a mathematical model of the entire link of micro-vibration transmission and then constructing the degradation mechanism of the micro-vibration image quality of space optical cameras.
