Abstract
Simultaneous measurement of temperature and strain without cross
sensitivity using a polarization maintaining fiber (PMF)
in a fi ber loop mirror (FLM) and a fiber Bragg grating (FBG) is presented. The sensing head is formed by inserting a FBG to
the PMF FLM. This sensor can not only be multi parameter identification simultaneously, but also eliminate cross sensitivity.
Experimental results show that the proposed sensor has the temperature sensitivity of 1.5096 nm/°C and strain sensitivity of
0.01042 nm/ με, respectively..
