In this letter, we propose a high resolution temperature insensitive interrogation technique for FBG sensors where one FBG acts as an edge filter to interrogate a separate FBG sensor. A high resolution of better than 5 me in strain measurement range from 0 to 1100 me and the best resolution of bette

## 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 Brag
