Education of Physics Experiment using Michelson Interferometer

迈克尔逊干涉仪实验是引入相对论和光干涉理论的一个重要时代。在这个项目中，我们的目标是考虑一个迈克尔逊干涉仪的物理实验课程，使用最新的设备，更简单，更容易引入教育激光，光学设备，数据采集系统和计算机。研究了如何做好实验辅导，培养大学生的实验设计能力。在第一财政年度，我们用光学元件构造干涉仪。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。在第二财政年度，目标是一个反馈设计课程。我们组成了多个干涉仪，并使用镜后的电动执行器测试反馈。根据反馈的成功，对本科生的辅导程序进行了测试。典型情况下，作动器标定精度为3- 5%。去年，电子反馈电路被安装到第一台干涉仪中。我们对薄膜电动执行器装置进行了测试，并成功地使用它来测量位移。我们认为，迈克尔逊干涉仪是能够用于教育的工具，为这样一个电子设备。

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.
