Two-Dimensional Deflection Maps by Using Fiber Bragg Grating Sensors
In this work, a novel technique to estimate the deflection of a bi-dimensional structure by means of fiber Bragg gratings (FBGs) is proposed. FBGs are embedded in monitored structure, avoiding the complex wiring typical of strain gauges, and provide local strain measurements. Then, by classical beam theory, from the strain maps measured by the FBGs, the two-dimensional deflection map of the monitored structure is numerically provided. The proposed method allows to overcome the difficulties existing in the direct measurement of the deflection: many types of structures (small and large) can be monitored in real-time thanks to this technique by using appropriate design parameters. In particular, this method can be useful in the structural monitoring of civil infrastructures and composite materials for aeronautics.
