Abstract :
For the communication from the aerial platform with the autonomous underwater vehicles, a laser Doppler vibrometer is under developing. The detection of the laser Doppler shift of the sea surface vibrating is implemented. The sound-pressure level of 150.8 dB is obtained under the acoustic signal of 7 kHz.
