| 摘 要： | 文章论述了基于反斯托克斯／斯托克斯比值的分布式光纤温度传感器系统，对其信号处理技术进行了全面而深入的研究。采用光时域后向散射技术来获取温度信息，并用时域信号数字积累平均方法来提高系统的信噪比，据此建立了分布式温度传感器。

| Abstract: | The distributed fiber optic sensor system based on the ratio of the Raman anti- Stokes to Stokes and the signal processing techniques of distributed fiber optics sensor are presented in the paper. The distributed optical fiber temperature sensor is set up by using the technique of optic time-domain reflection (OTDR) to get temperature information, and the way of getting the mean by the accumulating time-domain signal to improve the ratio of signal to noise. |
