wavelength is designed，which includes a set of magnetic drive device，light intensity automatic detection

module，and the system has the function of finding peak automatically，so the real-time processing and display of

data are realized. The magnetic suction transmission solves the problem of the difference between the axes of the motor

rotating shaft and the interferometer handwheel，reduces the motor jitter，uses the single chip microcomputer to

drive the stepping motor to rotate the handwheel of the interferometer，records the waveform of the interference light

intensity change in real time，reduces the interference caused by the instrument jitter through the algorithm，

realizes the automatic measurement of lightwave wavelength，reduces the experimental error，and uses the display

screen to display the experimental data in real time. The step angle of the stepper motor is used to record the displacement

value of the mirror，and the data results are calculated automatically，which makes the experiment more

intuitive and simple.
