Lateral direction acoustic detection of fiber optic sensor array using Fabry-Perot

Fabry-Perot을 이용한 두 개의 광섬유 센서배열의 횡방향 음압 감지 특성

To detect external acoustic signal, fiber optic sensor array using Fabry-Perot interferometer which had benefit of minimize and light-weight was used. The sensor head has 1cm in length, total length of fiber is 9.5cm, and the sensor supported at both ends, simply. External sound applied in lateral direction and detected two signals were compared each other. It was confirmed that the Fabry-Perot interferometric sensor array detected acoustic signal, effectively.
