A composite microstructure in fiber Bragg grating (FBG) with film deposition for hydrogen detection is presented. Through ablated to FBG cladding by a femtosecond laser, straight-trenches and spiral micro-pits are formed. A Pd鈥揂g film ...
Dynamic measurements instead require the use of glass optical fibre and FBG sensors. High frequency measurements are necessary to capture a structure response to events such as earthquakes and many SHM methods are based on dynamic measurements. For civil structures, a minimum interrogation frequency of...
Different sensor design, implementation and packaging methods, advantages and limitations of using FBG based sensors in different projects are reviewed. Comparative analysis of using two mathematical methods for the prediction of ground movement using FBG sensor data are also carried out. The two ...
