摘要: 折射率是介质的一个重要光学参数,对折射率的测量是光学实验中一个重要的组成部分.本实验利用双棱镜和平板玻璃制成的双空气劈尖作为盛放液体的容器,并在迈克耳孙干涉仪上增加了横向传动装置来控制双空气劈尖的移动 ,设计了一种测量液体折射率的实验装置.该实验方法避免了复杂的元器件加工,操作简便且测量结果较精确.

关键词: 液体折射率, 双空气劈尖, 迈克耳孙干涉仪

Abstract:


 The refractive index is an important optical parameter of the medium,and the

measurement of the refractive index is an important part of the optical experiment. In

this experiment,a biprism and a flat glass are used as a container for liquid,a lateral

transmission device is added to the Michelson interferometer to control the movement of the

double air wedge,so an experimental device for measuring liquid refractive index has

been de- signed. This experimental method avoids complicated component processing. It is easy to

operate and has more ac-curate measurement results.

Key words: liquid refractive index, double air wedge, Michelson interferometer
