电视跟踪测量设备光学系统参数的优化设计

OPTIMAL DESIGN FOR THE OPTICAL SYSTEM PARAMETERS OF A TRACKING AND MEASURING TELEVISION EQUIPMENT

光学系统参数对电视跟踪测量设备的综合性能起着决定性作用。光学参数的选取不仅要 满足设备的技术指标要求，还要考虑生产加工和实际使用的需要。从分析像点位移引起测角误差与 焦距的关系以及ＣＣＤ靶面光照度与通光口径的关系着手，用满足信号检测的调制对比度作为判据， 探讨光学参数优化设计的方法。

The optical system parameters of a tracking and measuring television equipment play an important role in deciding its comprehensive performance. The choice of the parameters are not only required to meet the demand of performance index of the equipment but to consider the requirement of manufacturing and operating as well. With the analysis for the relationship between an angle measuring error caused by pixel shift and focal length as well as between illumination on CCD target and clear opertare, and with modulation Contrast satisfied for signal detection as criterion, optimum design of optical parameters is discussed.
