Title
(EN) MULTIPLE ENERGY X-RAY SOURCE AND INSPECTION APPARATUS EMPLOYING SAME
(FR) SOURCE DE RAYONS X MULTI-ENERGIE ET APPAREIL D'INSPECTION ASSOCIE
Abstract
(EN)
A multiple energy x-ray source capable of rapidly generating and delivering x-rays in the form of successive pulses that alternate between at least two different energy levels, as well as a multiple energy x-ray inspection apparatus for inspecting moving objects that employs such a multiple energy x-ray source, are provided. The inventive x-ray source facilitates the use of differential absorption characteristics as a means for distinguishing materials contained within objects during a moving inspection.
(FR)
L'invention concerne une source de rayons X multi-énergie permettant de générer et de distribuer rapidement des rayons X sous forme d'impulsions successives qui alternent entre au moins deux niveaux d'énergie différents, ainsi qu'un appareil d'inspection de rayons X multi-énergie servant à inspecter le déplacement d'objets au moyen d'une telle source de rayons X. La source de rayons X de cette invention permet de faciliter l'utilisation de caractéristiques d'absorption différentielle en tant que moyen de distinction de matières contenues au sein d'objets, lors d'une inspection de déplacement.
