| 摘 要： | 基于"法布里-珀罗(F-P)干涉仪测量钠灯波长差"物理教学实验,介绍了法布里-珀罗干涉仪的基本工作原理;针对干涉圆环调节难度大和微调鼓轮改变光程操作耗时长给教学中操作者带来视觉疲劳以及导致测量误差增大的问题,提出改进操作方法,分别给出了逐步放大法调节干涉条纹以及微调和粗调鼓轮混合调节法来提高实验效率。通过对比实验数据结果和引入Matlab软件进行线性拟合误差分析的方法,验证了鼓轮混合调节法是一种能够提高实验效率同时保证数据测量准确性的可行方案。

| Abstract: | Based on the physics teaching experiment of measuring the wavelength difference of sodium lamp with the Fabry-Perot(F-P) interferometer, the basic working principle of Fabry-Perot interferometer is introduced. In view of the difficulty of adjusting interference rings and the problem of visual fatigue and measurement error caused by the change of optical path operation time of fine-tuning drum wheel in teaching, an improved operation method is proposed. The step-by-step enlargement method for adjusting interference fringes and the mixed adjustment method of fine-tuning drum wheel and coarse-tuning drum wheel are presented to improve the experimental efficiency. By comparing the experimental data and introducing the method of linear fitting error analysis with the software of Matlab, it is proved that the Drum-wheel hybrid adjustment method is a feasible scheme which can improve the experimental efficiency and ensure the accuracy of data measurement. |
