In this paper, we presented a waveform reconstruction method based on the self-mixing interference of DFB fiber laser by phase modulating technique, which is superior to the traditional vibration measurement system due to the wider measurement range and higher accuracy. In our sinusoidal phase modulation technology, the vibration information of the external target is extracted by the Fourier transformation method. For restoring the micro-vibration of the external target effectively with high precision, theoretical analysis and numerical simulations of phase modulation method based on the Distribution Feedback Bragg fiber laser are introduced in detail.
