| Abstract: | For application in fire monitoring, the distributed optical fiber temperature measurement system based on Raman scattering has a unique advantage of making up for the deficiency of the traditional thermal detector. This paper introduces the temperature measurement principle based on Raman scattering and space positioning principle based on optical time domain. A fire warning experiment was carried out, which showed that the distributed optical fiber temperature measurement system based on Raman scattering can well realize fire warning function for building heights within a certain range. |
