光纤Bragg光栅水听器的实验研究

Experiment and research of fiber Bragg grating hydrophone

根据光纤Bragg光栅的传感原理,提出了一种新型水听器———膜片式光纤Bragg光栅水听器,并对其可行性进行了研究。实验表明:膜片型光纤光栅水听器可准确检测水声信号。

Based on the sensing principle of fiber Bragg grating,a novel hydrophone-fiber Bragg grating membrane hydrophone has been proposed. Researches have been done about the possibility of this hydrophone. Experiments show that such hydrophone can detect underwater sound accurately.
