摘　　要：针对迈克尔逊干涉实验教学中光路调试难度大、仪器精度要求高、实验操作耗时较长等特点,基于光的干涉原理,根据等倾干涉和等厚干涉的光强分布,通过Matlab软件分别对迈克尔逊干涉仪的等倾干涉和等厚干涉实验进行了模拟仿真,观察了各自相关参数对干涉条纹图样的影响,通过实验验证,仿真结果与实验结果基本相符。教学实践表明,Matlab软件仿真和光学实验操作的有机融合,激发了学生的好奇心和科学探索的精神,有效地提高了课程的学习效果。In view of the characteristics of difficult light path debugging,high instrument accuracy requirements and long time-consuming experimental operation in Michelson interference experiment teaching,the phenomenon of Michelson interference experiment is simulated by using Matlab software based on the interference principle of light and the expression of optical path difference in this study.The influence of relevant parameters on the interference fringe pattern are analyzed.The simulation results are basically consistent with the experimental results.The practice teaching results show that the combination of Matlab simulation and optical experiment operation can stimulates students’curiosity and the spirit of scientific exploration,so as to effectively improve the teaching effect of the curriculum.
