A two-wavelength fiber optics Michelson interferometric sensor has been employed to detect the vibration signal in a flexible beam. The synthetic wavelength and synthetic heterodyne detection schemes have been adopted for signal processing on optical phase detection. The active control technique was also developed and implemented to suppress the vibration signal that was generated from the piezoelectric transducer. A 38 dB suppression has been obtained.
