Based on the sensing theory of Brillouin optical time domain reflectometry(BOTDR)
the distributed optical fiber Brillouin temperature sensing system is built and is used to measure the temperature on the 4.25 km length optical fiber.The analysis of the experimental results shows that the system may determine the temperature at any points for a certain length optical fiber.The unitary method makes the experimental results more intuitionistic and more accurate.
