摘要: … Spontaneous backward Brillouin scattering is demonstrated to be a sensitive probe of fibre characteristics using a heterodyne detection technique. Relative differences in GeO2 concentration from fibre to fibre as small as 0.01% can be detected. … spontaneous Brillouin back scattering single-mode optical-fibre characterisation …
