摘要
基于弱反射光纤光栅的发展应用,提出了一种新型光纤光栅水听器系统,对其水声探测机理进行了研究,并建立了水声传感模型,推导了在不同应力模型下的水听器声压灵敏度公式,并进行了仿真分析,为在实际应用中提高水听器声压灵敏度提供了理论支撑。
Based on the development and application of weak reflective fiber grating,a new type of fiber Bragg grating hydrophone system is proposed,the mechanism of underwater acoustic detection is studied,the underwater acoustic sensing model is established,the sensitivity formula of hydrophone under different stress models is deduced,and the simulation analysis is carried out.The theoretical support is provided for improving the acoustic pressure sensitivity of the hydrophone in practical application.
