摘要
在迈克尔逊干涉仪一光路中固定一透明玻璃管,通过改变玻璃管内空气的压强来观察干涉条纹的"吞吐"数量,来计算空气折射率。本文将研究改变开放玻璃管内空气温度时,测量干涉条纹的"吞吐"数来测量空气折射率,为迈克尔逊干涉仪测空气折射率提供了一种新的思路和操作方法。
A transparent glass tube is fixed in a light path of Michelson's interferometer, by observing interference fringes 'throughput' when changing the air pressure inside the glass tube, to calculate the refractive index of air. This paper will measure the refractive index of air when changing the air temperature inside the transparent glass. The method provides a new idea to measure refractive index of air by Michelson's interferometer.
