Changes to the internal structure of pipe such as crack initiation and propagation will result in the abrupt redistribution of internal stress in which, causes acoustic emission (AE). Fibre Bragg Grating (FBG) has shown to be able to detect such AE events. FBG experiences a shift in its reflected wa...
