摘要：

Simultaneous measurement of strain and temperature using a long-period grating (LPG) and a polarization maintaining fiber (PMF) in a fiber loop mirror (FLM) is presented. The sensing head is formed by an LPG. The transmitted optical intensity from the FLM is linear with the variation of the strain. And the interference resonant dip has a blue shift with the increasing of the temperature. Experimental results show that the proposed sensor has the sensitivities of 0.0346 nm/degrees C and 1.82 x 10(-3) dB/mu epsilon within the strain range of 0-1300 mu epsilon, respectively.
