Abstract

This paper described the distributed optical fiber temperature sensing system based on Brillouin amplifier structure, which combined Brillouin amplifier effect with optical time domain reflection(OTDR). With the relationship of temperature and stimulated Brillouin frequency shift, we can obtain the temperature on each point. Based on this principle, some experiments were taken, then the linear relationship and experimental data were given, which provided powerful foundation for future research.
