摘要
光纤水听器因其特有的抗电磁干扰、体积小等特点,在军事、民用上已经得到广泛应用。但国内在光纤平面水听器方面起步较晚,尚无成熟产品获得应用。本文开展了光纤平面水听器的宽频带高灵敏度关键技术研究,对水听器进行有限元建模,并完成基于Michelson干涉仪光路结构的光纤平面水听器样品研制。样品测试结果显示,该水听器在500~7.5k Hz工作频带内灵敏度高于-138 d B,与仿真结果吻合,且样品一致性较好。同时该水听器还具有结构和工艺简单的优点,设计方案具有一定的可行性和实用性。
A fiber-optic hydrophone, with characteristics including immunity to electromagnetic interference and small size, has been widely spread in military and civil field. But it has been lately started and still had no manufactures interiorly. In this paper, the key technology of broad band and high sensitivity has been discussed. And the finite element analysis of the hydrophone has been used. Then, the fiber-optic planar hydrophone sample based on Michelson interferometer has been demonstrated. The experimental result has been presented that the phase sensitivity of the hydrophone had been beyond-138 d B at the frequency range of 500~7.5 k Hz, which has been compatible with the emulation result. The design project of the hydrophone, which had been simplified the structure and technique, has been reasonably feasible and practicable.
