Abstract

A method and device for spectrometry analysis and for extracting a primary diffuse spectrum from a diffusion spectrum of diffuse radiation, according to a diffusion angle, coming from a material exposed to incident radiation through a surface, that includes the application of a spectral response function organized in the form of a matrix (M), known as a correlation matrix, of which each value aij corresponds with a number of detected photons, with energy Ei, constituting the multiple diffuse radiation, when a photon is detected, with energy Ej, of the primary diffuse radiation.
