| 摘 要： | 分析了ROFDR分布式光纤温度传感器和ROTDR分布式光纤温度传感器的理论模型、算法和各自的特点，指出Rofdr分布式光纤温度传感器可以降低噪声、获得高的信噪比、测试时间短，和ROTDR分布式光纤温度传感器相比有明显的优势。最后对比了ROFDR分布式光纤温度传感器的仿真结果和别人获得的ROTDR分布式光纤温度传感器的实测结果，显示出ROFDR分布式光纤温度传感器非常低的温度误差和非常高的空间分辨率，也表明了ROFDR的诱人前景。

| Abstract: | This paper analyzes the theoretical models, algorithms and characteristics of the fully distributed fiber optic sensors based on Raman optical-fiber frequency-domain reflectometry and time-domain reflectometry. Compared with the ROTDR sensor, the ROFDR sensor has the advantage of reduced noise, adequate SNR and short measurement time. Furthermore, the computation result shows a clearly low temperature error and a high spatial resolution of the ROFDR sensor, indicating its promising future. |
