| 摘 要： | 设计了对偏振衰落不敏感的迈克尔逊干涉型光纤水听器,系统通过使用直接调制光源的相位载波零差检测方式实现了光纤水听器相位载波(PGC)解调,并给出了实验测试结果。由2个水听器组成水听器阵进行了水池实验,结果显示:该干涉型光纤水听器有明显的指向性,具有一定的潜在实际应用前景。

| Abstract: | Interferometer Michelson fiber-optic hydrophone which doesn't sensitive to the polarization fading is designed.Through using phase generated carrier(PGC) technique and direct source modulation,the PGC demodulation of fiber-optic hydrophone is realized by the fiber-optic hydrophone system and the output result is reported.In addition,the experimental polar charts of matrix consisted of two Michelson fiber-optic hydrophones under the sound test are given and compared with the polar chart of simulation.The results show the interferometric Michelson fiber-optic hydrophones have a good performance on direction information,and thus have a potential application foreground. |
