    摘要： The invention relates to a device for identifying a material of an object comprising: a source of X photons (10) and a spectrometric detector (11), the source irradiating the object (100) with an incident beam (12) and the detector measuring a magnitude of a backscattered beam (13) from the incident beam after diffusion in a volume (δV) of the material and an energy of the X photons of the backscattered beam, the incident and backscattered beams forming an angle of diffusion (θ); a means (101) for adjusting the position between the source, the detector and the object in order for the volume to be at different depths with a constant angle, a means (102. a) for processing the two magnitudes in two positions and the energy in one position and for calculating an attenuation factor (μ
