Abstract
(EN)
A hand-holdable inspection device (10) for three-dimensional inspection of a volume distal to a surface. The inspection device has a hand-holdable unit including a source of penetrating radiation (12) for providing a beam (14) of specified cross-section and a detector arrangement (46) for detecting penetrating radiation from the beam scattered by the object (36) in the direction of the detector arrangement and for generating a scattered radiation signal. Additionally, the inspection device has a controller (48) for characterizing the volume based at least on the scattered radiation signal. The detector arrangement includes one or more backscatter detectors that may be disposed asymmetrically with respect to the beam and at differing displacements with respect to the surface.

L'invention porte sur un dispositif de contrôle portable permettant de faire un examen tridimensionnel d'un volume éloigné d'une surface. Ce dispositif de contrôle comporte une unité portable comprenant une source de pénétration du rayonnement de façon à générer un faisceau d'une section transversale déterminée et un dispositif de détection permettant de détecter la pénétration du rayonnement provenant du faisceau diffusé par l'objet dans la direction du détecteur et de générer un signal de rayonnement diffusé. Ce dispositif de contrôle possède également un contrôleur permettant de caractériser le volume en fonction au moins du signal de rayonnement diffusé. Le dispositif de détection comprend un ou plusieurs détecteurs de rétrodiffusion qui peuvent être agencés de manière asymétrique par rapport au faisceau et à des déplacements différents par rapport à la surface.
