摘要
针对迈克耳孙干涉仪以激光为光源测量玻璃板折射率所产生的异常现象,本文从几何光学理论出发进行了讨论,简明直观地给出了干涉条纹吞吐转折点与零光程点、光程、虚光源相对位置之间的关系,并与实验数据进行了对比.
While Michelson interferometer and laser are used to measure the refractive index of glass pane,there is an abnormal phenomenon. When we put a glass pane into one side of the light path,we observe an abnormal phenomenon of equal inclination inference rings puff. In this letter,we analyze the phenomenon in terms of geometrical optics and make clear the relationship between the turning point of interference fringe,zero light path difference and the relative location of virtual light sources. We also perform comparative analysis with experimental data.
