摘要
在传统迈克尔逊干涉仪的基础上,设计安装了一个带有石英窗口的盛液槽和一套三维可调悬臂动镜组件,利用等倾干涉原理,测量了水和不同质量分数葡萄糖溶液的折射率。结果表明,该仪器在保证测量准确度的前提下,测量精度高,操作简单,易于调节,便于维护,并且应用广泛。该实验既可以在实验教学中作为一个基于迈克尔逊干涉仪测量气体和液体折射率的扩展实验,也可以应用于实际生产测量。
Based on the traditional Michelson interferometer,a liquid tank with a quartz window and the module of three dimensional adjustable cantilever moving mirror is designed and installed.The refractive index of water and different concentrations of glucose solution are measured by using the isoclinic interference principle.The results indicate that the instrument possess the advantages of high measuring precision,simple operation,easy to adjust,easy to maintenance and widely used,under the premise that the measurement accuracy is guaranteed.The experiment can be used as an extension experiment based on Michelson interferometer to measure the gas and liquid refractive index in the experimental teaching.It can also be applied to practical production measurement simultaneously.
