title = "Localized strain measurements using an integration method to process intensity reflection spectra from a chirped FBG",
abstract = "A chirped fiber Bragg grating was used to measure the non-uniform strain profile of a notched aluminum specimen used to simulate a cracked structure. The specimen was subjected to tensile tests that produced regions of non-uniform strain near the notches. Analysis of power reflectance spectra from the grating, through the use of an integration method, enabled the strain profile near the notches to be determined. Unlike other intragrating sensing methods, this method did not require a disturbance hypothesis to be postulated. The strain profile results from this intragrating sensor were in reasonable agreement with predictions from modeling conducted using the finite element method.",
