Education of Physics Experiment using Michelson Interferometer

迈克尔逊干涉仪实验是引入相对论和光的干涉理论的一个重要时代。在这个项目中，我们的目的是考虑与迈克尔逊干涉仪的物理实验课程，使用最新的设备，更简单，容易介绍教育激光，光学设备，数据采集系统和计算机。我们研究了如何进行实验辅导，为大学本科生培训实验设计。在第一个财政年度，我们用光学元件构建了干涉仪。并与现有的干涉仪进行了比较。作为入门课程，我们尝试了“以太”问题的附加测试。在第二个财政年度，目标是反馈设计课程。在此基础上，我们制作了多个干涉仪，并在反射镜后采用电动执行器对反馈进行了测试。根据反馈的成功情况，对本科生的辅导程序进行了测试。在典型情况下，致动器校准的精度为3 - 5%。去年，第一台干涉仪配备了电反馈电路。我们对薄膜电致动器进行了测试，并成功地用它测量了位移，我们认为迈克尔逊干涉仪可以作为这类电致动器的教学工具。

The Michelson interferometer experiment is an important epoch for the introduction to the theory of relativity and interference of the light. In this project, we aimed to consider a curriculum of physics experiment with the Michelson interferometer, using recent devices that is simpler and easy to introduce the education laser, optical devices, data acquisition system and computer. We studied how to do the tutorial of experiment, to training the design of the experiment for the under-graduated students of the university.In first fiscal year, we construct the interferometer with optical components. Moreover, we compare it with ready-made interferometer for a demonstration. As an introductory curriculum, we tried the additional test of "Ether" problem.In Second fiscal year, the aim is a feedback design curriculum. We make up more one interferometer and test the feedback using electric actuator behind the mirror. According to the success of the feedback, the tutorial procedure for the under-graduated students was tested. The accuracy of the actuator calibration was 3-5 % for typical case.Final year, the electric feedback circuit was provided into the first interferometer. We tested the thin film electric actuator device, and successful to measure the displacement using it. We thought that the Michelson interferometer is capable to use for the educational tool for such an electric devices.
