Abstract

When a optical fiber Bragg grating is subject to a strain gradient, it's reflective spectrum will not only be transferee. but also be distorted because of the chirp of the grating. We used the T-matrix formalism to calculate the influence of different strain gradients on the reflective spectra of Bragg grating and have under-taken experiments to test these calculations. This confirmed that optical fiber Bragg grating can be used to test strain gradients and can be thought of as quasidis?tributed strain sensor.
