광섬유 센서를 이용한 수중 유연관의 변형 특성 파악

Abstract

This research is about the measuring technique of underwater tube's bending degree and presents an experimental result performed by novel designed fiber optic microbend sensor. Through the experiment, it was found that the optical power loss increased as the bending degree of tube increased. Because the suggested sensor can generate same level of microbend effect at the both directional bend of underwater tube, it is efficient to be applied to the underwater tube which tends to be multidirectionally bended.
