基于多功能干涉仪的教学演示及测量应用

摘要

为更方便观测干涉法测量的实验现象及理解实验原理,利用现有的迈克耳孙干涉仪,设计了多功能干涉仪,实现了教学仪器与智能精确测量仪器相结合,能直观地观测到干涉现象,并可测量气体的折射率随温度的变化.%To observe the experimental phenomenon and learn expediently the experimental principle, a multifunctional interferometer was designed based on the traditional Michelson interferometer.It combined experiment teaching with intelligent precise measurements.With this new interferometer, the interference phenomena were observed and the changes of the refractive index of air were measured which caused by the changes of temperature.
