中文摘要	two fiber grating sensors for high-temperature measurements are proposed and experimentally demonstrated. the interrogation technologies of the sensor systems are all simple, low cost but effective. in the first sensor system, the sensor head is comprised of one fiber bragg grating (fbg) and two metal rods. the lengths of the rods are different from each other. the coefficients of thermal expansion of the rods are also different from each other. the fbg will be strained by the sensor head when the temperature to be measured changes. the temperature is measured based on the wavelength-shifts of the fbg induced by the strain. in the second sensor system, a long-period fiber grating (lpg) is used as the high-temperature sensor head. the lpg is very-high-temperature stable co2-aaser-induced grating and has a linear function of wavelength-temperature in the range of 0 - 800 degrees c. a dynamic range of 0 - 800 degrees c and a resolution of 1 degrees c have been obtained by either the first or the second sensor system. the experimental results agree with theoretical analyses.
