A Fiber-Optic Air-Backed Mandrel Hydrophone
带空气腔芯轴型光纤水听器特性研究

An optical-fiber air-backed mandrel hydrophone was proposed and investigated both analytically and experimentally.The two-dimensional and three-dimensional quazistatically theoretical models of the hydrophone were created and compared,and the phase sensitivity of the hydrophone was analyzed.Twenty-two hydrophones of this type according to the model presented were constructed and tested.The experiment results show that the estimation of theoretical models are correct,and estimation accuracy of three-dimensio...
