Interferometric Optical Fiber Sensors for Health Monitoring Systems of Structures

구조물 유지관리용 간섭형 광섬유 센서

In this paper, the possibility of interferometric shows very good linearity to the strain. Fiber optic sensors have various merits for health monitoring systems. They are very small in diamerter. So, they don't give any disturbance in strength to the structures, Optical fiber sensors are innert to the electro-magnetic field. Therefore, fiber optic sensors give us a good solution to the electro-magnetic field. Therefore, fiber optic sensors give us a good solution to the maintainance systems of the structures, which are exposed to the electric fields, such as bridges, dams and buildings.
