摘　　要：为实现准确快速测量光源角分布,设计了放大率固定、曝光量无需调节的测量方法及其装置。该装置包括定焦成像系统和平移光源的直线系统。通过直线系统运动获取光源在不同位置的成像,通过饱和度选取有效光斑,利用平面成像与空间几何关系分别拟合了X、Y轴向的角分布函数与角度归一化分布图;并扩展到空间分布,绘制其三维图像;该方法高效准确、可视化程度高。For achieving an angular distribution quickly and accurately, the detection method is proposed and the measuring device is designed.For this method, the magnification is fixed and it＇s no need to adjust the exposure.The device includes a fixed focus imaging system and a linear motion system.The light source image at different locations is obtained by the movement of the linear system.The effective spot by the saturation is selected.Angular distribution function is derived by using planar imaging and geometry relationship.Angle distribution function and normalized distribution of X and Y axis are fitted.The three-dimensional image is drawn.This method is efficient, accurate, and has high degree of visualization.
