摘　　要：在高校开设的众多大学物理实验课程中,迈克耳孙干涉仪实验一直是学生较为棘手的实验。实验中需要目测记录快速移动的细圈,既累又容易出错,影响实验的准确度。结合迈克耳孙干涉仪的结构特点,设计开发了基于手机App的迈克耳孙干涉仪实验数据自动记录装置,可以实现对干涉条纹的自动精准计数,对仪器示数的快速拍照和存储,以及对激光波长测量数据的自动化快速处理。实验结果表明装置减少了人眼疲劳导致的干涉条纹计数误差,提高了测量的精确度;缩短了实验时间,提高了实验效率;有助于激发学生的学习兴趣。Among the college physics experiment courses offered by many colleges and universities,the Michelson interferometer experiment has always been a difficult experiment for students.Combined with the structural characteristics of the Michelson interferometer,an automatic recording device for the experimental data of the Michelson interferometer based on the mobile phone App was designed and developed.It can realize automatic and accurate counting of interference fringes,rapid photographing and storage of the instrument readings,and automatic and rapid processing of laser wavelength measurement data.The experimental results show that the device reduces the interference fringe counting error caused by human eye fatigue,improves the measurement accuracy,shortens the experiment time,improves the efficiency of the experiment,and stimulates students’interest in learning.
