A simultaneous measurement system of temperature and strain is proposed using a long period fiber grating(LPFG) and a high-birefringence fiber(HBF) loop mirror,based on their resonant wavelengths corresponding to different temperatures and strain sensitivities.Based on the theoretical analysis,the resonant wavelength response sensitivities to temperature and strain for long-period fiber grating and high-birefringence fiber loop mirror are experimentally determined,respectively.And then,the corre...
