摘　　要：可见光电视测量系统主要用于对可见光波段的目标进行实时测量,即将视场中目标偏离光轴的角度大小检测出来,送伺服系统,形成闭环,由跟踪架带动电视测量系统跟踪目标,使得脱靶量减少,将目标始终锁定在电视视场之中.详细介绍800 mm可见光测量电视分系统的各个部分的机械结构设计,并对其视轴精度进行了定性分析,得出了视轴误差公式和产生视轴误差的误差源.The visible light measurement system is mainly used to the real-time measurements of visible light band, that is to say it tests the angular size from which the goal of field deviate the light axis, then sends it to servo system to form a closed loop. The tracker frame drives the tracking television measurement system to track the target to make the target miss volume reduced and keep the target locked in the field of television. The mechanical structure design of 800 mm visible light measurement of television sub-systems is introduced in detail, and the visible axis is qualitatively analyzed. The formulas of axial error and the errors that produce axial error are derived.
