AbstractA novel acoustical-vibration signal detection system based on laser Doppler is proposed. The system is based on the M- Z interferometer optical system, and used more adaptive piezoelectric ceramics modulation and demodulation system to restore signal. The whole system satisfies the requirements of non-contact, remote, high sensitivity and anti-interference. It has the advantages of strong stability, compact light path, low cost and easy miniaturization compared with heterodyne interferometer based on Acoustical Optical Modulator(AOM). At last the influence of the laser power fluctuations(frequency instability and amplitude instability) on the system is analyzed theoretically.?2011 SPIE.
