Advanced x-ray systems for nondestructive inspection and contraband detection

摘要

High-energy X rays provide the capability for examining the interior of large, complex objects, measuring densities and dimensions, finding flaws, and detecting contraband. Although various types of X-ray imaging systems have been in use for some time, recent developments have greatly extended the envelope of capabilities. Two ARACOR X-ray vision systems will be discussed that offer new and advanced capabilities for contraband detection and nondestructive evaluation. The Eagle is a new mobile, transportable, high- efficiency X-ray imaging system designed for inspection cargo and detecting drugs, explosives and weapons at seaports, airports and border crossings. ARACOR's line of industrial computed tomography systems provide quantitative 3D X-ray images for such applications as the inspection of Minuteman and Peacekeeper solid rocket motors, the safety and security of nuclear weapons, and metrology and failure studies of automobile components and castings. Newly developed software enables the accurate reverse engineering of complex parts to form CAD descriptions and the direct input of image data into rapid prototyping systems for the production of replacement parts.
