利用蓝宝石光纤和/或石英光纤与红宝石传感头机械连接的热探头，研究了光纤材料对光纤温度计性能的影响。蓝宝石光纤红宝石传感头的光致发光寿命及其温度系数(/SPLtau/=3.9ms和-9.9/SPLu/S/K)与使用石英光纤的略有不同(/SPLtau/=4.2ms和-10.9/SPLu/S/K)，这是因为蓝宝石光纤的背景光致发光。采用基于双指数方程拟合光致发光衰减曲线的修正寿命计算方法，成功地减小了蓝宝石光纤光致发光对温度测量的影响。
The influences of fiber materials on the performance of the fiber-optic thermometers are evaluated using the thermal probes, in which the sapphire fiber and/or the silica fiber was connected mechanically with the ruby sensor head. The value of photoluminescence (PL) lifetime and its temperature coefficients for the ruby sensor head with sapphire fiber (/spl tau/ = 3.9 ms and -9.9 /spl mu/s/K) were slightly different from those using the silica fiber (/spl tau/ = 4.2 ms and -10.9 /spl mu/s/K), due to the background PL from the sapphire fibers. The influence of the PL from the sapphire fiber on the temperature measurements can be reduced successfully using a modified lifetime calculation based on the curve fitting of the PL decay with double exponential equation.
