Abstract
La présente invention a pour objet un dispositif de modulation de spectre d'énergie, un procédé et un dispositif de discrimination de matériau, et un procédé de traitement d'image, qui peut discriminer le matériau dans des objets de dimensions importante et moyenne, en utilisant des rayonnements X ayant des niveaux d'énergie différents, sont décrits.Ce dispositif (2) comprend une première partie de modulation de spectre d'énergie (202) destinée à moduler un premier rayonnement ayant un premier spectre d'énergie et une seconde partie de modulation de spectre d'énergie (203) couplée à la première partie de modulation de spectre d'énergie et destinée à moduler un second rayonnement ayant un second spectre d'énergie différent du premier. La présente invention peut être utilisée pour une inspection sans ouverture de conteneurs de grande dimension.
