Spontaneous Brillouin scattering
Ultra long range Brillouin Optical Time Domain Analysis
... In order to overcome the cited problem, we propose the use of a sensing scheme that doubles the fiber length connected to the BOTDA sensing unit while only half of it is employed for sensing purposes [103]. Under this ...
