Abstract	A novel all-fiber heterodyne Laser Doppler Vibrometry (LDV) for acousto-optic communication has been developed in this paper. A line width of 1 kHz single mode continuous fiber laser, two acousto-optic frequency shifters (AOFS), two balanced photodetectors and one telescope with 30 mm aperture were used in this LDV. Using the above system setup, the 6 kHz signal can be reconstructed by detecting the vibration of a glass sticking on the piezoceramic transducer (PZT). The proposed vibration measurement technique proved to be very accurate and potential to acquire the acoustic signal by experimental results.
