Abstract :
The basic principle of temperature sensor based on fiber Bragg grating (FBG) is analyzed. A fiber Bragg grating temperature sensor is designed and produced. Using fiber Bragg grating as the sensor, fiber Bragg grating analyzer to demodulation the wavelength shift, the relationship between FBG wavelength shift and temperature is measured. Experimental result shows that the temperature sensitivity of fiber Bragg grating temperature sensor is 12.2pm/°C.
