Analysis of the Pressure Phase Sensitivity Response of the Air-backed Mandrel Fiber-optic Hydrophone
芯轴型光纤水听器声压相移灵敏度响应分析

A structural model of a air-backed fiber-optic hydrophone is proposed and the response of the pressure phase sensitivity is investigated.The interaction relation between optical fiber and elastic tube is gained by the acoustic analyses of the principle and basic structure of the air-backed mandrel hydrophone.Then the equivalent model of the dynamics,the theoretical model of the pressure phase sensitivity and dynamic response model of the fiber-optic mandrel hydrophone are obtained.Also based on the finite e...
