摘　　要：光纤分布式传感器技术是指利用光纤的相关物理特性对被测场的空间和时间行为进行实时检测。该技术对于大型结构的应变场分布和温度场分布的检测有重要使用价值。在世界各地从事光纤传感器技术研究的学者的不懈努力下,已经研究开发成功了多种类型的分布式传感器系统,并已经有部分产品应用于生产实践中。本文详细地阐述了光纤分布式传感器的基本原理,并简要地介绍了不同种类的光纤分布式传感器系统的系统组成。The Distributed Optical-Fiber sensing technology is that using some correlative physical characters of the fiber optics to test the real-time spatial and temporal behavior of the measuring physical field.The technology possesses high value in measuring strain field and temperature field of a huge mechanical structure. Various kinds of Distributed Optical-Fiber sensors are worked out or partially applied in manufacture with the great efforts of the world-wide scholars. The basic principle of the Distributed Optical-Fiber sensors is discussed in this paper. And various in kind of Distributed Optical-Fiber Sensors are introduced in brief as well.
