Abstract

To set up the arrays system of FBG(Fiber Bragg Grating) Hydrophone sensor and realize the multi-point signal detection for the wide scope underwater, using WDM(Wavelength Division Multiplexing) method and Passive band-pass filter system, underwater acoustic signal detection of the newly designed two FBG Transducers is successfully experimented. As a result of the experiment, it was possible each signal with different frequent signals is detected for the multi-point up to 1.3KHz in underwater. We can, therefore, prove the possibility on the system design of Hydrophone sensor arrays, using the newly made FBG Transducers.

FBG (Fiber Bragg Grating) hydrophone sensor의 arrays system을 구축하고, 수중에서 넓은 영역에 대한 다중점 신호 검출을 구현하기 위하여, WDM(Wavelength Division Multiplexing) 방법과 passive band-pass filter system을 이용하여, 설계 및 제작된 2개의 FBG transducers의 수중 음향파 신호 검출을 실행하였다. 실험 결과 수중에서 주파수 1.3 KHz대까지 다중점에 대하여, 주파수 신호가 각각 다른신호의 검출이 가능하였다. 따라서, 제작된 FBG transducers을 이용한 hydrophone sensor arrays의 시스템 설계가 가능함을 확인하였다.
