| Abstract: | A temperature and pressure measurement method is introduced, which is based on a cantilever with single fiber Bragg grating as the sensing element. And the measurement result impact of the non-linear relationship between temperature and wavelength is analyzed. Then the linear and nonlinear application scope of reflection wavelength and temperature is given.The linear application scope of wavelength and temperature of bare grating part and pre-strain part is -11.2℃ |
