摘要

A sensing head configuration and the necessary interrogation parameters to simultaneously measure strain and temperature using a single fiber Bragg grating (FBG) are presented and demonstrated. By writing the FBG in a linearly etched fiber, we were able to use the information encoded in the peak wavelength and in the spectral width of the FBG. The spectral width of the grating depends uniquely on the applied strain and is temperature independent. An uncertainty of Â±15.26 Â¿Â¿ and Â±1.92Â°C was achieved in the experimental verification.
