摘要： 以辐射度量为标准,建立了CCD像机探测合作目标光功率模型以及功率方程,得到了所需合作目标光功率与CCD像机参数的制约关系,分析了CCD像机探测到光点所占像元数与传输距离之间的关系。用超焦距方法解决了CCD像机对有限远距离范围内工作时的成像清晰度问题,采用了像方远心光路设计解决了系统测量精度问题。研究了太阳光进入CCD像机视场和照射对接口反射后对CCD像机产生的影响。

Abstract: With radiometry as a standard,cooperative targets opto-power models and equation of CCD camera detection were established.The restrictive relationship between cooperative targets opto-power and CCD camera parameters was obtained.Imaging definition which CCD camera works in limited distance was solved by using hyperfocal distance.Telecentric optical system was employed in order to solve the precision of measuring systems.The relationship of pixel number CCD camera detect and operating distance was analyzed.It is studied what influences CCD camera when the sun radiates FOV of CCD camera and mechanic part of docking reflects from the sun.
