摘要
普通的迈克尔逊干涉仪测量空气折射率遇到的主要问题是由于光程差太大,使得干涉条纹很密无法计数。该文介绍的用测微目镜将干涉条纹放大,再进行测量的方法很好地解决了这个问题。
When common Michelson interferometer is used for measuring air refractive index, there is a major problem that the optic path difference is so large that the fringes is to close too count. A method that prior to measurement the fringes are amplified by using micrometer eyepiece is presented in this paper for resolving the problem.
