Abstract
Two kinds of fiber optic vibration sensors for civil structure vibration monitoring are proposed in this paper. The first is based on the detection of spatial mode speckle of a multi-mode optical fiber. A multi-mode optical fiber, diameter is 200/230 μm, is used in the present experiment. The second method uses an e-core two-mode optical fiber. The experiment on a composite beam with an embedded statistical fiber optic sensor and surface mounted e-core two-mode fiber optic sensor are demonstrated. The experimental results show that the two types of the fiber optic vibration sensors have higher sensitivity compared to piezoelectric sensor along with other benefits of fiber optic sensor, including lower cost.
