Abstract
In this work, we present a fiber Bragg grating interrogation based on high‐birefringence fiber loop mirror for strain–temperature discrimination. Due to spectral response of the optical filters it is possible to determine the variation of the wavelength and the optical power of the Bragg grating sensor when subject to strain or temperature. Maximum errors of ±0.4°C and ±12 με are reported over 80°C and 2000 με measurement ranges. © 2006 Wiley Periodicals, Inc.
