(TU Delft Structural Integrity & Composites) Contributor Kalli, Kyriacos (editor) Brambilla, Gilberto (editor) O'Keeffe, Sinead (editor) Date 2019 Abstract Fibre Bragg grating sensors have gained a lot of attention in damage detection and strain measurement applications in the past few decades. These applications include matrix crack detection and delamination tip monitoring in composite structures, crack detection in concrete and civil engineering structures and etc. The damage localisation accuracy of such methods, directly depends on precise knowledge on the position of the FBG sensor. However, this information is not commonly provided by manufacturing companies with such accuracy. In this paper, we propose a novel approach to accurately determine the position of an FBG sensor with a low complexity setup. The proposed method offers an accuracy of below 10 μm, and can consequently increase the spatial resolution of damage detection methods.
