In a photoelectric theodolite, the time delay of TV or IR miss distance will have a relative large influence on stability and tracking accuracy of the control system.
在光电经纬仪中，电视或红外脱靶量的滞后对控制系统的稳定性和跟踪精度都有较大的影响。
A kind of short distance wireless communications technology, ir communications is widely used for its low cost.
红外通信是一种价格低廉、适应范围比较广的短距离无线通信技术。
When using the IR sensor, the size of the target in the imaging plane of the camera is only one pixel or several pixels and the signal received is very weak when the target is far away in distance.
对于红外传感器来说，当距目标很远时，目标在成像平面上仅占一个或几个像素，且接收到的信号很微弱。
