Distributed optical fiber sensing technology based on Brillouin scattering is the hot spot at home and abroad. The time-domain-based Brillouin distributed optical fiber sensing technology is mainly divided into Brillouin optical time-domain reflectance and Brillouin optical time-domain analysis of two. Domestic research on distributed optical fiber sensing technology based on Brillouin optical time-domain reflectometry has been reported in China. The research status of distributed optical fiber sensing technology based on Brillouin optical time-domain analysis technology is introduced, and two sensing technologies based on time-domain positioning are analyzed and compared. The problems existing in the practical application of Brillouin scattering distributed optical fiber sensing technology and the possible solutions are summarized, and the further development direction of the sensing technology is pointed out.
