光学跟踪和测距系统和其它系统相比具有其优越的地方,这是由于它固有的光频能量的空间效率。平面偏振的、相干涉的激光光束可以能够原先所不可能得到的光能的控制。利用激光跟踪,所述的这个系统可以以200c/s的实时采样速度给出精确的跟踪和斜距信息。把一个镜片系统安装在主跟踪架上构成的复合轴伺服系统,通过跟踪装在目标上的激光照射的反射器,可以提供角度数据。到目标反射器的斜距由一个数字式的、调频的、CW-激光测距系统来决定,它的分辨率和采样速度处于独立控制之下。
Optical tracking and ranging systems have their advantages over other systems due to their inherent spatial efficiency of optical energy. Plane-polarized, coherent laser beams can be controlled by light energy that was previously impossible. Using laser tracking, the system described can provide accurate tracking and slant range information at real-time sampling rates of 200c / s. A multi-axis servo system with a lens system mounted on the main tracking shelf provides angular data by tracking the laser-illuminated reflector mounted on the target. The slant range to the target reflector is determined by a digital, frequency-modulated, CW-laser ranging system whose resolution and sampling speed are under independent control.
