Abstract :
A fiber sensor configuration suitable for simultaneous measurement of temperature and strain is investigated. The sensor consists of a high-birefringence fiber loop mirror concatenating with an erbium-doped fiber. By monitoring the peak power variation and peak wavelength shift, it is feasible to simultaneously measure temperature and strain.
