Landau Placzek ratio applied to distributed fibre sensing

Wait, P.C. and Newson, T.P. (1996) Landau Placzek ratio applied to distributed fibre sensing Optics Communications, 122, (4-6), pp. 141-146. (doi:10.1016/0030-4018(95)00557-9).

It is shown experimentally that the ratio of the intensities of Rayleigh and Brillouin backscattered light (Landau Placzek ratio) in an optical fibre has a temperature dependence which may be used for the basis of a distributed temperature sensor. This result, combined with the known frequency dependence of be Brillouin backscattering on temperature and strain, indicates that spontaneous Brillouin backscatter may be used for the unique determination of either temperature or strain in a distributed optical fibre sensing system.
