摘　　要：本文阐述了光纤温度传感器的工作原理及其在水库水位监测中的应用。系统采用拉曼光时域反射技术对所测点进行定位,通过测量光缆表面的温度分布,得到了水温并且判定出水库水位。根据具体情况的精度要求,采用不同的光缆铺设方式,既满足了精度又降低了成本。测试结果表明,定位精度可以达到10mm。The principle of Distributed optical fiber Temperature Sensor （DTS） and its application in water level detection is discussed in this paper. The system can obtain water temperatures and also determine water level through measuring the surface temperatures of the optical fiber. Different manners of laying optical fiber are used according to specific precision requirements, which meet the precision requirement and reduce the cost. Test result shows that the positioning precision can reach to 10mm.
