中文摘要	A structure model of the air-backed fiber-optic hydrophone was proposed and the frequency characters of the hydrophone were investigated. The interaction relation between optical fiber and elastic tube was gained by the analyses of the principle and basic structure of the air-backed mandrel hydrophone. Then the theoretical model of the resonance frequency was obtained by creating the dynamics model. On the basis of the analysis of the parameters of the model, main restrictively factors and the improved methods were proposed. According to structure which was proposed, the mandrel fiber-optic hydrophone was produced with determined parameters, and the 3 dB bandwidth achieves about 30 kHz in the test, so the results validate the theory model.
