摘要
强度调制型光纤水听器以其结构简单、易于实现、成本低、信号处理方便等特点而成为近年来光纤水听器研究领域中的热点。全面而系统地论述和分析了基于强度调制原理的各种光纤水听器的结构、原理和性能特点,并提出了一种基于单模光纤耦合器技术的新颖的光纤水听器原理。
Intensity-modulated fiber-optic hydrophones have become a hot spot in research on fiber-optic hydrophones in recent years due to their simple structure and low cost. This article presents a comprehensive and systematic overview of fiber-optic hydrophones based on light intensity modulation. A novel fiber-optic sensor for acoustic wave measurement on the basis of a single-mode fiber coupler is also introduced.
