Abstract: An inspection system based upon an imaging enclosure characterized by an enclosing body, or skin. A source of penetrating radiation and a spatial modulator for forming the penetrating radiation into a beam, are both concealed entirely within the body of an enclosure such as a shipping container for convenient operational deployment. Multiple modules, such as for providing power and for enclosing an operator console may be coupled to the imaging enclosure. An image is formed of the contents of the object based in part on the scatter signal and the relative motion signal. A detector, which may be separate or part of the scatter detector module, may exhibit sensitivity to decay products of radioactive material.

Abstract: A system for inspecting an enclosure. A source generates a beam of penetrating radiation that is characterized, at each instant of time, by a power spectrum of intensity as a function of energy. A first module conveys the source along the length of the enclosure while a detector, coupled so as to move in coordination with the first module, detects the beam of penetrating radiation after the beam interacts with the object and generating a detector signal. A beam shaper modifies the instantaneous power spectrum of the beam of penetrating radiation. The first module and the detector may be coupled by a gantry straddling the enclosure. Other modules may be coupled to move with the first module.
