在分布型光纤拉曼光子温度传感器（ＤＯＦＲＰＴＳ）系统中，自发拉曼光子是温度信息的载体，在２ｋｍ光纤上实时采样１０００个点，用于空间温度场分布的测量。系统采用拉曼光时域反射技术，对所测点进行定位。对分布光纤拉曼光子温度传感器系统的测温精度进行了讨论，由系统的信噪比来确定测温精度，提出了改善测温精度的方法，实际系统的测温精度达±１℃。
In the distributed fiber Raman photonic temperature sensor (DOFRPTS) system, spontaneous Raman photons are the carriers of temperature information, and 1000 points are sampled in real time on the 2km fiber for the measurement of spatial temperature field distribution. The system uses Raman optical time-domain reflectometry technology to locate the measured points. The temperature measurement accuracy of the distributed fiber Raman photon temperature sensor system is discussed. The temperature measurement accuracy is determined by the signal to noise ratio of the system. The method of improving the temperature measurement accuracy is put forward. The actual temperature measurement accuracy of the system is ± 1 ℃.
