摘　　要：分析和比较Stokes光、Anti-Stokes光和Rayleigh光的温度效应,表明Anti-Stokes光是分布式光纤温度传感系统中最佳的温度解调对象。针对温度信号解调方法,从温度灵敏度、标定温度的选取以及待测温度范围三个方面进行详细的分析对比,获得有意义的结论,为温度解调方式的选取提供了理论基础。Absrtact: The temperature effects of Stokes light,Anti-Stokes light and Rayleigh light are analyzed and compared. Theoretical analysis reveals that Anti-Stokes light is the best temperature demodulation object in distributed optical fiber temperature sensing system. According to the demodulation method of temperature signal,a series of meaningful conclusions are drawn by means of detailed analysis and comparison from three aspects such as temperature sensitivity,the selection of calibration temperature and the range of temperature to be measured,which might provide a theoretical basis for the selection of temperature demodulation method.
