【Abstract】 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.更多还原
