Abstract
Vibration of the interferometer signal is amplified and fed back to the laser diode after photo-electronic conversion, which controls the injection current of the laser diode. By using the character that the output frequency of the laser diode changes linearly with the injection current, the output frequency can be modulated by the injection current. Through this, phase vibration is compensated and interference pattern is stabilized. This paper describes the formula of the stability. The stabilization factor is measured and the main factors that affect the stability is described. These can supply references to the adjustment of the interferometer, the feedback module and the stability of the interferometer.
