摘要

基于单片机技术，对迈克尔逊干涉仪测量热膨胀系数的实验进行了优化。首先利用条纹识别系统对迈克尔逊干涉条纹进行自动识别，再通过温度探测器实现自动测温，最后通过计算机编程实现了热膨胀系数的数据计算。通过将单片机、计算机编程等技术引入到大学物理实验当中，实现了实验数据的可视化、计算智能化，使得对热膨胀系数的测量与计算更为方便快捷。同时，将大物实验器材运用到实际实验之中，也拓展了迈克尔逊干涉仪的应用范围。

Abstract:

The experiment of measuring the coefficient of thermal expansion by Michelson interferometer is optimized based on the microcontroller technology.Firstly, the automatic recognition of Michelson’s interference fringe is realized by using the fringe recognition system ,then the automatic temperature measurement is realized by using the temperature detector,and finally the data calculation of the coefficient of thermal expansion is realized by computer programming.By introducing the microcontroller and computer programming technologies into the university physics experiment,the visualization of the experimental data and the intelligent calculation are realized, which makes the measurement and calculation of the coefficient of thermal expansion more convenient and faster.At the same time,the application of Michelson interferometer is expanded by applying the large object experimental equipment to the actual experiment.

Key words: Michelson interferometer microcontroller programming automatic identification system
