基于迈克尔逊干涉仪原理,提出了在非平静水面情况下探测中低频水下声信号的激光干涉方法。利用携带声波信息的散射光和参考光的干涉结果提取水下声信号的频率信息,并进行了理论分析和实验验证,结果表明,激光干涉法可以准确探测出中低频水下声信号的频率信息。 Based on the Michelson interferometer principle, a laser interferometry method is proposed to detect underwater and mid-range underwater acoustic signals under non-calm water conditions. The frequency information of the underwater acoustic signal is extracted by the interference result of the scattered light and the reference light carrying the acoustic wave information, and the theoretical analysis and experimental verification are carried out. The results show that the laser interferometry can accurately detect the frequency information of the underwater acoustic signal .
