Abstract

The strain and temperature sensing performance of FBG are studied in the temperature range of 123K to 273K by the experiment. The temperature sensitive, strain coefficient and cross-sensitivity coefficient of the sensors are derived analytically and verified by experiments. It is found that they are nonlinear. Cross sensitivity increase with lower temperature. At a constant temperature, the Bragg wavelength shift is linear with the longitudinal strain within the range of 5000 micro strains.
