Abstract

The Brillouin scattering in combination with frequency-domain analysis is a new sensing technique for the distributed measurement of temperature and strain. Comprehensive theoretical examinations and experimental results of distributed temperature and strain measurements demonstrate the feasibility of this new concept. In an experimental demonstration a spatial resolution of 3 m was achieved for an 11-km-long single-mode fiber.
