Demodulation Technique Based on Laser Interference for Weak Photo-Acoustic Signals on Water Surface
To detect underwater sound-generating targets, a water surface acoustic wave laser interference and signal demodulation technique is proposed in this paper. The underlying principle of this technique involves casting a laser beam onto the water surface disturbed by an underwater acoustic source and...
