This paper investigates the pressure sensitivity of an interferometric fiber - optic hydrophone element with a concentric mandrel including an enhanced sensitivity layer based on the theory of elastic mechanics and finite element method ( fem ) and then investigates its harmonic frequency and vertical directional property using fem, and verifies all the results derived from theoretic analysis at last
本文分別基於彈性力學的理論和有限元的方法對含彈性增敏層的同軸干涉型光纖水聽器基元的聲壓靈敏度進行研究,並基於有限元的方法對其諧振頻率和垂直指向性進行分析,最後用實驗對各項分析結果進行了驗證。The analytic result derived by studying the vertical directional property shows that, the vertical sensitivity distribution is homogeneous and the fluctuation is 0 db in theory. the fluctuation observed in experiments is less than 0. 3db, which agrees well with that in theory
垂直指向性分析結果表明,光纖水聽器垂直方向的靈敏度分佈是均勻的,理論上波動應為0db ,而實驗測得的垂直方向的指向性波動小於0
