摘　　要：对激光探测水下声信号可行性进行了研究.水下声信号造成的水表面微扰导致了反射的激光光通量的变化,探测器接收到的光通量的变化频率与水下声信号的频率相同,并给出了探测器位置与接收光通量的关系.A research was made on detecting underwater acoustic signals using laser. The surface perturbations generated by underwater acoustic signal result in the luminous flux change of a laser beam reflected. The experimental results showed that the variations of the luminous flux received by the detector had the same frequency as the acoustic signal.
