摘要： An angular analysis system that can be controlled to receive radiation at a defined angle from a defined focus region. The angular analysis system is used for level 2 inspection in an explosive detection system. Level 2 inspection is provided by a three-dimensional inspection system that identifies suspicious regions of items under inspection. The angular analysis system is focused to gather radiation scattered at defined angles from the suspicious regions. Focusing may be achieved in multiple dimensions by movement of source and detector assemblies in a plane parallel to a plane holding the item under inspection. Focusing is achieved by independent motion of the source and detector assemblies. This focusing arrangement provides a compact device, providing simple, low cost and accurate operation.

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： A method for detecting nuclear species in a sample by adaptive scanning using nuclear resonance fluorescence may comprise illuminating the target sample with photons from a source; detecting a signal in an energy channel; determining a scan evaluation parameter using the signal detected; determining whether the scan evaluation parameter meets a detection efficiency criterion; adjusting one or more system parameters such that the scan evaluation parameter meets the detection efficiency criterion; and comparing the signal in an energy channel to a predetermined species detection criterion to identify a species detection event. In another embodiment, detecting a signal in an energy channel may further comprise detecting photons scattered from the target sample. In another embodiment, detecting a signal in an energy channel may further comprise detecting photons transmitted through the target sample and scattered from at least one reference scatterer.

摘要： A baggage scanning system and method employ combined angular and energy dispersive x-ray scanning to detect the presence of a contraband substance within an interrogation volume of a baggage item. The interrogation volume is illuminated with penetrating, polychromatic x-rays in a primary fan beam from a source such as a tungsten-anode x-ray tube. An energy-dependent absorption correction is determined from measurement of the attenuation of the fan beam at a plurality of different energies. Radiation coherently scattered by substances in the interrogation volume is detected by an energy-resolved x-ray detector operated at a plurality of scattering angles to form a plurality of scattering spectra. Each scattering spectrum is corrected for energy-dependent absorption and the corrected spectra are combined to produce a scattering pattern. The experimental scattering pattern is compared with reference patterns that uniquely characterize known contraband substances. The system and method can locate and identify a wide variety of contraband substances in an accurate, reliable manner. The system provides for automated screening, with the result that vagaries of human performance are virtually eliminated. False alarms and the need for hand inspection are reduced and detection efficacy is increased.

摘要： A method and an apparatus for liquid safety-detection by backscatter with a radiation source relate to a radiation detecting technology field. The invention comprises using a radiation source, a collimator, a detector, a data collector and a computer data processor, and has the main steps of: 1) a liquid article to be detected being placed onto a rotatable platform; 2) the ray emitted from the radiation source causing Compton scattering at the surface of the liquid after passing through the package layer of the liquid article; 3) the scattering photons being received by the detector after passing the collimator; 4) the detector transmitting the received data to the data collector; and 5) the data collector transmitting the amplified and shaped data to the computer data processor, which processes the data to obtain the liquid density of the detected article, then compares the result with the densities of dangerous articles in a current database, and gives warning if finding that the density of the detected article is consistent with that of a dangerous article. Comparing to the prior art, the invention has a convenient use, a rapid and accurate detection, a strong anti-interference, a high use safety and reliability, and an easy protection.

摘要： The present invention provides for an improved scanning process having microwave arrays comprised of microwave transmitters in radiographic alignment with microwave receivers. The microwave array emits controllably directed microwave radiation toward an object under inspection. The object under inspection absorbs radiation in a manner dependent upon its metal content. The microwave radiation absorption can be used to generate a measurement of metal content. The measurement, in turn, can be used to calculate at least a portion of the volume and shape of the object under inspection. The measurement can be compared to a plurality of predefined threats. The microwave screening system can be used in combination with other screening technologies, such as NQR-based screening, X-ray transmission based screening, X-ray scattered based screening, or Computed Tomography based screening.

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.
