The invention relates to a method of characterizing a scattering medium. According to the invention, the processing on the electromagnetic radiation scattered by the scattering medium is carried out for an unpolarized signal. In this way, only the anisotrophic incoherent transport of radiation induced by the scattering medium is obtained in the characterization according to the invention. According to the invention, the data representative of the angular variation of the first image representing the unpolarized scattered radiation is representative of the purely isotrophic part of the scattering. Having obtained this purely isotrophic part, it is then possible, according to the invention, to calculate a second image representative of the non-isotrophic part of the scattering. This non-isotrophic part represents the anisotrophic transport of radiation induced by the medium at the moment of scattering.
