公共诊断搭载平台双CCD交汇瞄准系统

 CCD交汇测量作为一种非接触式坐标测量技术，在对空间目标进行坐标定位的应用中显示出其独特的优越性。建立公共诊断搭载平台双CCD交汇瞄准系统模型，设计了瞄准成像系统和瞄准调节系统，其中瞄准光学系统物高8 mm，物方分辨率8.3 μm，在61 lp/mm时MTF高于0.5，瞄准调节系统采用双脚万向节机构，完成系统二维指向的调节，通过对采集视频图像的处理，为搭载的诊断设备提供精确的指向。误差分析结果表明：该系统的瞄准精度可以达到16 μm，可安装在公共诊断搭载平台前端。

Double CCD intersection positioning system for public diagnosis carrying platform

As a non-contact measurement technique, charge-coupled device (CCD) intersection measurement is used for the coordinates positioning of flying targets. The model of the double CCD intersection positioning system for public diagnosis carrying platform was established. The imaging system with the object height of 8 mm, the lens resolution of 8.3 μm and the MTF of greater than 0.5 at 61 lp/mm was designed for the positioning system, as well as the adjustment system which adopted double universal joints structure to achieve the 2D pointing adjustment and processed the video images to offer an accurate pointing to diagnosis equipment. The error analysis results indicated that the positioning accuracy of the system was better than 16 μm, and the system could be installed on the front end of the public diagnosis carrying platform.
