Raman-assisted distributed Brillouin sensor in optical fiber for strain and temperature monitoring in civil engineering applications
9th International Symposium on Measurement Technology and Intelligent Instruments, 29 June - 2 July 2009, Saint-Petersburg, Russia ; Investigation of a method to extend-range distributed temperature and strain sensor based on detection of the Brillouin frequency shift combined with counter-propagating Raman amplification has been realized. 50-km-range of standard single-mode silica fiber with great results has been sensed. Results of an experimental investigation of Brillouin frequency shift at different fibers. ; Ministerio de Educación y Ciencia ; Comunidad de Madrid
