摘　　要：本文将数字图像处理 (DIP)技术应用于塞曼效应实验中的图像处理 ,提出了利用边缘检测确定非均匀条纹峰值和利用鼠标定位切线法快速确定圆环半径的方法。建立了 CCD实时监测处理系统 ,编制了实用软件 ,方便地测定了电子的荷质比 ,其精度比胶片法提高The digital image processing (DIP) technology was used in Zeeman effect to analyze fringe patterns. The novel methods of determining non-uniform fringe peak by edge detection and measuring circle radii by tangent location by mouse are proposed. A real-time processing CCD system and practical software have been established. The result shows that the DIP system can measure the ratio of charge to mass of electron expediently and can greatly highten the accuracy by more than one order of magnitude compared with photograph method.
