摘要： 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.

摘要： 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.

摘要： Systems and methods for inspecting an object with a scanned beam of penetrating radiation are disclosed. Scattered radiation from the beam is detected, in either the backward or forward direction. Characteristic values of the backscattered radiation are compared to expected reference values to characterize the object. Additionally, penetrating radiation transmitted through the inspected object may be combined with scatter information. In certain embodiments, the inspected field of view is less than 0.1 steradians, and the detector is separate from the source of penetrating radiation and is disposed, with respect to the object, such as to subtend greater than 0.5 steradians in the field of view of the object.

摘要： An inspection system based upon an enclosed conveyance such as a van, capable of road travel, for inspecting objects of inspection that may include persons. The conveyance is characterized by an enclosing body, or skin. A source of penetrating radiation and a spatial modulator for forming the penetrating radiation into a beam, both contained entirely within the body of the enclosed conveyance, irradiate an object with a time-variable scanning profile. A detector module generates a scatter signal based on penetrating radiation scattered by contents of the object, while a proximity sensor generates a relative motion signal based on a relative disposition of the conveyance and the inspected object. 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.

摘要： An x-ray inspection system for identifying fissile material includes one or more sources of penetrating radiation that generate first, second, and third instantaneous spectra where the object is exposed to the second only if there is no penetration of the first and the object is exposed to the third only if there is no penetration of the second. Further, the source of the second and the third spectra is a source adapted to provide single pulses. Consequently, ambient levels of radiation may be held below cabinet levels while identifying objects containing fissile material.

摘要： A system and methods for characterizing regions within, or on, an inspected object, wherein a lower-Z scattering material and a higher-Z material may both lie along a common line of sight. The inspected object is scanned with penetrating radiation characterized by an energy distribution, and penetrating radiation scattered by the inspected object is detected in a manner that generates two detector signals that distinguish between materials of higher and lower effective atomic number under distinct sets of conditions with respect to the energy distribution of the penetrating radiation. An image is generated, based on a function of the two detector signals, as is a differential image, so as to allow distinction of higher-Z and lower-Z materials.
