Novel distributed fibre sensor using microwave heterodyne detection of spontaneous Brillouin backscatter
S.M.Maughan, H.H.Kee and T.P.Newson
A new distributed sensing technique using spontaneous Brillouin backscatter has been demonstrated. For the first time ever, direct 11GHz heterodyne detection allows measurements of both Stokes and anti-Stokes signals. Results have been obtained for a sensing fibre length of over 10km with a spatial resolution of 20m.
