Abstract
The differential modulation of the attenuation bands in a long-period grating is used for simultaneous sensing of axial strain and temperatu re. A grating fabricated in a conventional optical fiber is demonstrat ed for concurrent measurements of strain over a range of 2100 mu epsil on and temperature over a range of 125 degrees C, with maximum errors of 58 mu epsilon and 1 degrees C, respectively.
