Abstract: X-ray inspection of moving cargo based on acquiring multiple image lines at one time or substantially at one time. An X-ray source with multiple-beam electron beam targets creates multiple parallel X-ray fan beams. X-ray inspection systems and methods employ such multiple-beam sources for purposes of inspecting fast moving cargo.

Abstract: Methods for discriminating among x-ray beams of distinct energy content. A first volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides that convert the scintillation light to light of a longer wavelength. An x-ray beam initially incident upon the first volume of scintillation medium and traversing the first volume is then incident on a second volume of scintillation medium. The first and second scintillation media may be separated by an absorber or one or more further volumes of scintillation medium, and may also have differential spectral sensitivities. Scintillation light from the first and second scintillation volumes is detected in respective detectors and processed to yield a measure of respective low energy and high-energy components of the incident x-ray beam.

Abstract: A detector and methods for inspecting material on the basis of scintillator coupled by wavelength-shifting optical fiber to one or more photo-detectors, with a temporal integration of the photo-detector signal. An unpixelated volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides. This geometry provides for efficient and compact detectors, enabling hitherto unattainable geometries for backscatter detection and for energy discrimination of incident radiation. Additional energy-resolving transmission configurations are enabled as are skew- and misalignment compensation.

Abstract translation: 用于区分不同能量含量的x射线束的方法。 闪烁介质的第一体积将入射穿透辐射的能量转换成通过将闪烁光转换为较长波长的光的多个光波导从闪烁光提取区域提取的闪烁光。 最初入射到第一体积的闪烁介质并穿过第一体积的X射线束然后入射到第二体积的闪烁介质上。 第一和第二闪烁介质可以由吸收器或一个或多个另外的体积的闪烁介质分离，并且还可以具有差的光谱灵敏度。 在相应的检测器中检测来自第一和第二闪烁体积的闪烁光，并对其进行处理以产生入射的X射线束的各自的低能量和高能量分量的量度。
