[Abstract]:Facing the application field of Brillouin scattering temperature measurement, the Brillouin scattering monitoring principle is introduced in view of the relationship between Brillouin frequency shift and temperature value between nylon tight fiber and bare fiber under the condition of heating up of the same sensing line. The experimental scheme of nylon tight fiber and bare fiber based on BOTDA technology is designed. The slope and deviation of Brillouin frequency shift curve between Brillouin frequency shift and temperature are analyzed, the characteristics of Brillouin frequency shift curve and the variation law of frequency shift value at the same temperature are discussed, and the conditions suitable for temperature measurement of compact optical fiber are put forward.
