| Abstract: | The paper introduces the operating principle of phase modulation,analyzes the prime elements which influence the stability of demodulation signal.On this basis,an improved method is put forward and a set of perfect fiber sensing system is established. Through a lot of experiments and analysis,error is reduced and examination sensitivity becomes higher. |
