Paper Abstract

A simple and novel distributed tilted fiber Bragg gratings (TFBGs) based transverse load sensing system using optical frequency domain reflectometry (OFDR) is proposed and demonstrated for the first time. The transverse load compresses an elastomer material around the fiber and induces a broadband loss in the spectrum of the TFBG. The additional loss is directly measured by the return loss spectrum of Fresnel reflection points introduced in the Rayleigh backscattering trace. With the wavelength sweeping characteristic of OFDR, we realized distributed sensing by interrogating each of the TFBGs with different wavelengths and observed a minimum crosstalk effect between sensors.
