Abstract
We report an experimental study of a SMS fiber sensor for simultaneously measuring both displacement and temperature. By measuring both central wavelength spectral shifts and peak power variations, displacement and temperature can be independently determined with a demonstrated sensitivity to displacement of 0.62 μm and a temperature sensitivity of 1 °C by using a typical OSA which has a wavelength resolution of 10 pm and power measurement resolution of 0.01 dB.
