Abstract: An approach to improve the Zeeman effect experiment is introduced by using LabVIEW. To capture ex-periment images, the ActiveX is used in the LabVIEW, and digital image process technology is applied to reduce many interferers in the experiment images. The computer aided measurement in the charge-mass ratio of electron and the difference in wave numbers are realized. The measure accuracy is improved and the teaching effect is enhanced.

Key words: Zeeman effect, ActiveX, LabVIEW, image processing
