Abstract

To address the measurement of the overall mirror shape of the heliostat and the alignment angles of sub-mirrors in tower solar power stations, a heliostat mirror shape measurement method based on fringe reflection is proposed. This method utilizes four cameras to measure the heliostat composed of four reflective mirrors, reducing the size of the projection screen. The measurement principle of this method is described in detail, a measurement system is constructed, and the measurement uncertainty of the system is analyzed. Experimental results show that the normal deviation values of the measured heliostat in the X and Y directions are 1.004 mrad and 1.311 mrad, respectively, with a measurement uncertainty of 0.52 mrad.
