| 摘 要： | 分析了三线阵CCD立体测绘相机工作原理,设计了一种可工程化实施的测绘相机光机结构,此结构由3台相机互成角度装入测绘基座构成.单相机采用像方远心亚对称光学系统,由单镜组装入薄壁壳体的镜头、基于凸轮导向结构的调焦机构、基准镜和成像电器盒构成.测绘基座为测绘相机的高稳定支撑结构,采用7个筒单元、3个板单元与底座交错形成有机一体的结构形式.星敏支架为星敏感器的安装结构,采用3个简单元和一个圆锥单元相贯而成一体的结构形式.运用PATRAN/NAS-TRAN软件对测绘相机进行工程分析表明,测绘相机组合体的强度和刚度好,满足航天光学遥感器的要求.振动试验结果表明,测绘相机一阶固有频率大于100 Hz,不会与整星产生共振；通过各种环境试验后,相机间基准镜坐标系变化小于4″,测绘相机测量坐标系变化小于5″.通过在轨运行表明,测绘相机结构稳定,满足测绘精度要求.

| Abstract: | Through analyzing the principle of three-line-array CCD mapping camera,a kind of engineering implemented light-machine structure is designed,which consists of three cameras with space intersection angles.Every single camera adopts a telecentric and sub-symmetrical optical system,which is composed of lens units assembled to the thin shell,focusing mechanism based on a cam oriented frame work,fiducial mirror and imaging electrical equipment.The mapping pedestal is a steady support structure for the mapping ca... |
