CCD在塞曼效应中的应用及最佳灰度值的确定

THE APPLICATION OF THE CCD IN THE ZEEMAN EFFECT AND THE DETERMINATION OF THE BEST VALUE OF GRAY

用CCD观测系统取代传统的塞曼效应实验仪观测系统。对采集的图像进行分析并确定图像的最佳灰度值。不但提高了实验精度,而且缩短了实验时间。该实验方法对拓宽学生知识面,开发计算机的应用起到了一定作用,值得在其他实验中推广。

The CCD observation system insteads of the traditional experimental of Zeeman effect. The article analyses the collection pietures to ascertain the best value of the gray. The new method increases the sensitivity and resolution ratio remarkably. The method can make the students improve the insight and the application in computer, and is worth extending to some other experiments.
