Method and device for recognizing a material using its transmission function (original) (raw)

2009

Abstract

The invention relates to a method for characterizing the nature of a material, comprising: - disposing at least one sample (100) of this material between a source (1) of X-rays, and a detector; performing, using the X-ray source, N X-ray spectra transmitted through said material, each for a duration Δt; calculate the transmission function of this material as a function of the energy or the detection channel; in each of at least two energy zones, calculating the integral of the transmission function, thus forming at least a first transmission coefficient (α1) and a second transmission coefficient (α2).
