Simultaneous measurement of strain and temperature was demonstrated by using a long-period fiber grating inscribed on a polarization-maintaining fiber. This paper analyses the intersect senstive questions in terms of strain and temperature of fiber optic cable material. It also proposes a new way to carry out simultaneous measurements of strain and temperature. Experimental results show mean square deviations of 15.6 με and 0.7°C for strain and temperature, respectively.
