Abstract
The previously described approximated transfer matrix model (ATMM) provides insight into the strain distribution along on fibre Bragg grating (FBG) sensor. In this paper we study the influence of matrix cracks in composites on the angular frequency of the side-lobes of the FBG reflection spectra in frequency space.
