摘要
水下声信号在水-空气界面会引起表面波动而对打在水表面的激光进行调制。利用直接光强检测方法可以检测到受水下声信号调制的激光信号,本文用光线分析理论模型证明了利用激光进行水下声波探测的可行性。
The underwater acoustic signal can cause surface wave motion at the water-air interface and hence modulate the magnitude of the laser beam falling on the water surface. The modulated underwater laser signal can be detected by using a direct light intensity detection method. In this paper, the feasibility of the laser detection of underwater acoustic signals is verified on the basis of theoretical analysis.
