摘要： Effective structural condition monitoring, and the action from it, is likely to result in significant economic savings from a better determination of structural integrity and use of the structure itself. It is also essential for the enhanced prediction of structural service lifetimes based on real-time measurement data obtained. Fiber optic-based sensors have shown real promise for structural condition monitoring, due to the attractive features they possess, such as small size, geometric versatility, multiplexing capability, and resistance to corrosive and hazardous environments. As a result, these sensors have been explored widely for monitoring a wide range of structural materials, including composites, concrete, limestones, carbon/aluminum, and metals (Scott et al., 2013; Sun et al., 2012; Nguyen et al., 2014; Kerrouche et al., 2009a), and the key parameters that have been measured include temperature, strain, vibration, relative humidity, pH, and chlorides, and so on.
