【摘要】 分布光纤喇曼光子传感器（ Ｄ Ｏ Ｆ Ｒ Ｐ Ｓ） 系统是一种实时测量空间温度场、应力场和压力场的光纤网络系统。依据喇曼散射的温度效应，自发喇曼散射光子是温度信号的载体，瑞利散射光子是应力和压力信号的载体， Ｄ Ｏ Ｆ Ｒ Ｐ Ｓ 系统是一种特殊的光纤通信机，同时也是一种光纤雷达。文章讨论了系统的结构、解调方法、 Ｌ Ｄ 波长选择、系统的信噪比更多还原

【Abstract】 Distributed optical fiber Raman photonic sensor(DOFRPS) system is an optical fiber network used for the real-time measurement of temperature field,strain field and pressure field in the space.Spontaneous Raman scattering photons are the carriers of temperature signal and the Rayleigh scattering photons are the carriers of strain and pressure signal. DOFRPS system is a special optical fiber communication system, as well as a kind of optical fiber radar. The configuration and demodulation method of the DOFRPS system are discussed in the paper along with the selection of LD wavelength and signal noise ratio更多还原
