摘要: 干涉型光纤水听器作为一种新型水听器，与传统水听器相比具有诸多优点，能否精准获取水下声信号与所采用的解调算法密切相关。简要介绍了干涉型光纤水听器的结构及工作原理，重点对干涉型光纤水听器基于相位生成载波（Phase Generated Carrier）以及3×3耦合器解调算法的原理和进展进行了分析对比，阐述了主要解调算法的特点和相对优劣之处，并给出未来可能的研究方向。Abstract: Interferometric fiber optic hydrophones represent a novel class of hydrophones offering numerous benefits over traditional devices. The accuracy in capturing underwater acoustic signals is intricately linked to the employed demodulation algorithms. This paper briefly outlines the construction and operational principles of these hydrophones, with a focus on comparing and analyzing the principles and developments of demodulation algorithms, particularly the Phase Generated Carrier (PGC) and the 3×3 coupler approaches. It delineates the attributes, strengths, and limitations of these primary demodulation algorithms and proposes potential avenues for future research.
