A vibration sensor system based on Distributed Feedback Fiber Lasers (DFB-FL) and digital Phase Generated Carrier (PGC) demodulation is presented in this paper. The external sound signals is collected by DFB-FL, and then the signal is gathered into the computer and is processed. The sensing of the system need no power supply, so the system can deal with unexpected disasters. Moreover, the system can be used for remote warning.
