| Abstract: | The small volume fiber Bragg grating (FBG) sensor head designed by using especial package technique with polymer material has the function of simultaneous measurements of pressure and temperature, which can solve the temperature cross-sensitivity of FBG effectively. Simultaneous measurements of the pressure and temperature using only one grating based on the two reflective peaks with different pressure and temperature sensitivity coefficients through the process of packaging FBG are demonstrated. |
