Abstract

A novel and simple fiber Bragg grating (FBG) sensor for simultaneous displacement and temperature measurement is presented in this letter. The scheme used a specially constructed cantilever, and provided sensitivity coefficients of 8.22 X 104/mm and 8.86 X 105/°C for displacement and temperature measurement, respectively.
