摘要
塞曼效应是原子的能级在外磁场中出现分裂的现象,应用数字图像处理技术,对塞曼效应分裂谱线图像进行处理,将图像中具有一定宽度的干涉圆环条纹细化为单像素宽度的二值化图像,采用Hough变换方法实现了条纹直径的自动提取并求得荷质比。与理论值相比,荷质比的百分误差为0.26%。
Zeeman effect refers to the phenomenon that the spectral lines of atom split in the external magnetic field. By applying the technologies of image preprocessing, this paper mode the fringes thin with certain width in the splitting spectrum images to binary images with single-pixel width, extract diameter of fringe by way of Hough Transform and obtain the charge-mass ratio of electron. The percentage error is 0.26% when compared with theoretical value.
