摘　　要：针对恶劣环境下高温测量的需要,研究了一种新型光纤高温传感系统;该系统基于白光偏振干涉技术,以蓝宝石晶体为测温材料来进行温度测量,其测量温度可达1600℃。从蓝宝石晶体材料、测温原理、传感头结构设计以及信号处理方法等方面对测温系统进行理论探讨。最后,对测温系统进行了实验验证,利用现有实验条件证明了在0～700℃范围内该系统具有很好的测量精度。To meet the requirements for high-temperature measurement in harsh environment, a high-temperature optical fiber sensor based on the white light polarimetric differential interferometrie technology is proposed using single crystal sapphire,which can measure temperature up to 1600 ℃. The theory was analyzed from the aspects of single crystal sapphire materials, the principle of temperature measurement, the design of sensing probe and the signal processing method in the paper. The experiment of the temperature measurement system was carried out in the last. The results of experiment demonstrated the system had good precision from 0℃ up to 700 ℃.
