Jiang Yi Chen Weimin Yang Lichen Huang Shanglian(Dept. of Optoelectrivity Precission Instrument, Chong qing Univ. )
In this paper the theory of strain/ temperature sensor based on optic- fiber grating is presented. And its features have been carried out experimentally. The sensitivity of strain is 0. 66 pm/με and that of temperature is 5. 62 pm/ C. And by calculation, the former is 0. 62 pm/με; the latter is 5. 2 pm/C, with the light source wavelength of 827 nm. The both are in agreement on each pair of them. well.
