摘要

针对塔式光热电站定日镜整体面形检测和子镜拼接角度的测量,提出基于条纹反射法的面形检测方法,该方法使用4部相机测量由4面反射镜拼接而成的定日镜,减小了投影屏幕的尺寸;详细阐述该方法的测量原理,搭建测量系统,并分析系统的测量不确定度。实验结果表明：被测定日镜沿X方向和Y方向的法线偏差值分别为1.004和1.311 mrad;测量不确定度为0.52 mrad。

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.
