| Abstract: | For simultaneous distributed measurement of temperature and strain based on Brillouin scattering in optical fibers,there are mainly three effective ways: measuring the Brillouin intensity and Brillouin shift simultaneously,measuring two different Brillouin shifts and monitoring the temperature and strain based on the Raman scattering and Brillouin scattering.In this paper,the principles of these methods have been discussed thoroughly.Two schemes for Brillouin distributed sensing using direct detection and h... |
