Abstract: Methods for characterizing living plants, wherein one or more beams of penetrating radiation such as x-rays are scanned across the plant under field conditions. Compton scatter is detected from the living plant and processed to derive characteristics of the living plant such as water content, root structure, branch structure, xylem size, fruit size, fruit shape, fruit aggregate volume, cluster size and shape, fruit maturity and an image of a part of the plant. Ground water content is measured using the same technique. Compton backscatter is used to guide a robotic gripper to grasp a portion of the plant such as for harvesting a fruit.

Abstract: An x-ray inspection system using backscatter of an x-ray beam emitted through a scan panel contiguous with, but of a material distinct from, an enclosure that contains an x-ray source by which the x-ray beam is generated. The scan panel is contoured in such a manner as to be visibly blended with a shape characterizing the enclosure. In some embodiments, the beam traverses multiple scan panels, where one or more of the scan panels may be selected for beam filtration properties. The scan panel may be disposed interior to a sliding door, and may be structured to serve as a scatter shield.

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.
