Abstract
A novel laser tracking measuring system based on the principle of multi-lateration is developed. The system consists of a four-quadrant silicon photoelectric cell measuring the position of reflected beam from the target with sensitivity of 200mv/mm, a rotational tracking mirrror with a solid angle of 35 degrees driven by two motors and a new type of closed-loop control with digital PID and analog PID. The experiment shows that it works reliably with tracking speed 0.7m/s, and the standard deviation of measurement is 1.2μm.
