Abstract :
We report an experimental study of a SMS fiber sensor for simultaneously measuring both displacement and temperature. By measuring both peak wavelength spectral shifts and peak power variations, displacement and temperature can be independently determined with a demonstrated sensitivity to displacement of 16.14 pm/μm and a temperature sensitivity of 10.16 pm/ °C.
