Temperature sensing capacity of fiber Bragg grating at liquid nitrogen temperature
Temperature sensing capacity of fiber Bragg grating at liquid nitrogen temperature
摘要
Abstract
According to the temperature sensing model of the fiber Bragg grating (FBG), a theoretical method of temperature sensing capacity of FBG is proposed. Based on the temperature sensing model of FBG, a temperature sensing experiment was completed at liquid nitrogen temperature (2196uC). The theoretical and experimental results were compared and analyzed, which show that at liquid nitrogen temperature or in a large-scope temperature sensing, the relationship between thermal variation DT and relative shift of reflected center wavelength DlB/lB of FBG is nonlinear and conic multinomial.
