Abstract:
1. Portable and versatile device for non-destructive examination of an object, comprising: an X or gamma radiation source, adapted to radiography, at least one matrix detector, sensitive to X rays or gamma rays, that is large and finely pixelated, adapted to radiography, this detector having a large useful detection zone in which a square with sides of at least 20 cm will be inscribed, this useful zone being composed of small detection pixels, smaller than 300 gin, a shielding and collimation accessory, fitted on the X or gamma radiation source, to adapt it to backscattering imaging, wherein removable ring collimators provide different emission cones, at least one removable image formation accessory, based on the coded aperture imaging technique, this image formation accessory including a mechanical structure, preferably motor driven, comprising a large and finely pixelated coded mask on which a square with sides of at least 6 cm can be inscribed, this coded mask comprising small pixels smaller than 1000 gm, the structure being designed to be placed in contact with the detector for backscattering imaging or radioactive source imaging, and a system for the synchronised control of the X or gamma radiation source, the detector and the image formation accessory, and for data acquisition and processing in order to display an image in real time, which enables radiography of the object and/or backscattering imaging thereof and/or detection and localization of a radioactive source present in the object.
