Signal analysis of the distributed optical fiber Raman photon temperature sensor (DOFRPTS) system

The distributed optical fiber Raman photon temperature sensor (DOFRPTS) system is a new sensor system, use it for the measurement of temperature field in space on time. In this system, the spontaneous Raman photons is temperature signal's carrier, the optical fiber is transmitted medium, also is sensitive medium. The signal analysis of the DOFRPTS system has been discussed in this paper.
