Abstract
This paper introduces the advancement and the developing direction of the Brillouin scattering distributed optic fiber sensor. Principles of the Brillouin scattering distributed optic fiber sensor as well as schemes of BOTDR sensor, BOTDA sensor and BOFDA sensor that based on OTDR are illustrated. Furthermore the problems in existance is pointed out, and the development and trend are shown.
