    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: A system and method for inspecting an enclosure with penetrating radiation. Radiation side-scattered from an object within the enclosure is detected, allowing the object to be located. If the object is deemed suspect, a volume element of the suspect object is further irradiated with penetrating radiation, and radiation coherently-scattered by the volume element is detected. The energy spectrum and angular distribution of the coherently-scattered radiation are used to characterize the volume element of the suspect object.

    摘要: A system and method for inspecting an enclosure. A beam of x-rays is used for scanning the enclosure and for identifying areas of suspect material. The beam is subsequently coherently scattered off suspect materials, during the course of a single pass of the enclosure past the beam, for uniquely discriminating innocuous from contraband substances. One or more energy dispersive detectors measure radiation coherently scattered by an identified volume of suspect material. Absorption effects of the energy distribution of the coherently scattered radiation are compensated by means of a fiducial reference disposed between the interrogated object and the detectors.

    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 sources of the second and the third spectra are pulsed. Consequently, ambient levels of radiation may be held below cabinet levels while identifying objects containing fissile material.

    摘要: Systems and methods for detecting clandestine fissile or radioactive material on the basis of emitted radiation and particles (such as neutrons and alpha particles) arising from within the material. Emission by the fissile or radioactive material is detected in conjunction with a conventional x-ray imaging system that includes an external source of illuminating penetrating radiation, at least one detector configured to detect at least the penetrating radiation and to generate a detector signal, and a processor configured as a detector signal discriminator to generate an output indicating whether the detector signal is triggered by an origin other than illuminating penetrating radiation. Active and passive modes of detection are described by some embodiments. Other embodiments are directed toward neutron detection, gamma ray detection with energy resolution, and designs of detectors to enhance the detection of clandestine nuclear material.

    摘要: An inspection system for inspecting a moving vehicle and for detecting material disposed within the vehicle. The system has a source for providing a generally horizontally pointing beam of penetrating radiation of specified cross-section so as to illuminate vehicles driven alongside the source of radiation. A detector arrangement, disposed between the source of radiation and the moving vehicle detects radiation from the beam scattered by any material disposed on the underside of the moving vehicle and generates a scattered radiation signal that may be used for characterizing the material disposed within the vehicle.

    摘要: An inspection system for inspecting a vehicle moving at a grade of travel over a surface and for detecting material disposed within or on the underside of the vehicle. The system has a source for providing a generally upward or downward pointing beam of penetrating radiation of specified cross-section so as to illuminate vehicles driven above or below the source of radiation. A detector arrangement, disposed below the grade of travel, detects radiation from the beam scattered by any material disposed on the underside of the moving vehicle and generates a scattered radiation signal that may be used for characterizing the material disposed on the underside of the vehicle. Similarly, a detector arrangement disposed above the vehicle generates a scattered radiation signal that may be used for characterizing the material disposed within the vehicle.
