| 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. |
