摘要
简要介绍法布里-珀罗标准具的结构和原理之后,利用Matlab模拟研究了其干涉图样.重点模拟了反射层反射率、间隔层厚度、间隔层折射率、光束入射角以及波长对干涉图样的影响.最后利用图像模拟形象地解释了自由光谱范围和精细度两个概念.将有助于读者更好地理解塞曼效应中标准具的原理和作用.
After the brief introduction of the structure and principle of Fabry-Pérot interferometer,Matlab is used to simulate the interference patterns. Simulation is mainly focused on the effect of reflectivity,spacer layer thickness,refractive index,the beam incident angle and wavelength on the interference patterns. Finally,the two concepts of free spectral range and fine degree are vividly explained by the Matlab simulation. This work will help readers to better understand the principle and function of Fabry-Pérot interferometer in Zeeman effect experiment.
