基于分布式光纤温度传感器的热源定位方法
Heat Source Locate Method Based on Optical Fiber Temperature Sensor
摘要
Abstract
The advantage of optical fiber temperature sensor in temperature measurement is analyzed, and the signal processing method of optical fiber temperature sensor based on the ratio of Anti-Stokes and Stoke is discussed. And a signal processing algorithm, based on the signal time delay estimating and a source signal at distributed optical fiber temperature sensor array, is proposed to resolve the problem of heat source location under planar or circular wave-fronts. According to the difference of planar and circular wave-fronts, the far-field and near-field algorithm can be used respectively to identify the location of heat source. Experimental results indicate the feasibility of proposed algorithm.关键词
