Study on Dynamic Performance Parameters of Laser Tracker Based on Self-Developed Circular Trajectory Generator System

The laser tracker has characteristics of high measurement accuracy and wide range. Laser technology, as an effectively large-scale measuring approach, plays a critical role in dynamic measurement. Currently, the static performance trackers been well studied. However, remain unclear terms evaluating its performance. circular trajectory generator system can quantify tracker. We developed standard using stable servo then conducted in-depth study on through statistical analysis. Numerous experiments have shown that if is set at equal spacing, indication error smallest when distance 3 m, indicating fitted diameter m closest to generator. If with sampling frequency, 5 m. When low speed, spacing points fixed proportional number points, while or speed frequency proportionally points. These conclusions will facilitate application
