Abstract

This paper proposes a heliostat tracking error measurement method based on the spiral motion trajectory of the light spot. This method involves controlling the rotation of the heliostat to make its reflected light spot follow a spiral trajectory. The spot images are captured by a camera and processed to ultimately determine the heliostat’s tracking error. The principle of the spiral trajectory method for measuring heliostat tracking error is elaborated. An experimental platform for measuring heliostat tracking error is established

and the camera light-target method is used to verify the correctness of the spiral trajectory measurement method. The results show that the measurements from the spiral trajectory method are largely consistent with those from the camera target method. The root mean square deviations of the measured azimuth and elevation tracking errors between the two methods are 0.016° and 0.018°

respectively.
