Abstract The safe and stable operation of the transformer is affected by internal temperature. Therefore, it very necessary to accurately effectively detect temperature winding. To realize effective detection transformer, a fiber optic sensor based on structure multimode (MMF)–no core (NCF)–multimode (MMF) (i.e., MMF–NCF–MMF) studied. sensitivity reaches 0.0313 nm/°C. Moreover, enhance accuracy...
A novel fiber optic sensing technology for high frequency dynamics detection is proposed in this paper, specifically tailored for structural health monitoring applications based on strain wave analysis, for both passive impact identification and active Lamb wave monitoring. The sensing solution relies on a fiber optic-based interferometric architecture associated to an innovative coherent detec...
A highly sensitive temperature sensor was made by use of a side-hole glass fiber filled with indium metal, and its optical properties were investigated. The temperature sensitivity of the fiber-optic temperature sensor was dλ/dT=-7.38 nm/K. The temperature sensitivity was also examined in sensors made by different lengths of the side-hole fiber and the indium-filled fiber region. The temperatur...
