分布光纤Raman光子传感器系统的优化设计
The Optimum Design of Distributed Optical Fiber Raman Photon Sensor(DOFRPS) System
【摘要】 本文从新的解调方法、LD激光波长选择、光纤取样环修正方法出发,分析讨论了系统的优化设计。取得的主要实验结果如下:测温范围0~120℃;测温不确定度±2℃;温度分辨率0.1℃;光纤绕组探头的空间分辨率<5cm,在2km光纤上可采样1000个点
【Abstract】 The optimum design of DOFRPS system is researched in the paper.The new demodulated method of system,the choice of laser wavelength,the correct method of the sample’s loop are discussed.The main experimental results is following:the measurement temperature range:0~120℃;the temperature accuracy:±2℃;the temperature resolution:0.1℃;the spatial resolution of optical fiber coil probe is less than 5 cm and the 1000 points are sampled on 2 km optical fiber.
