Abstract: An inspection system, including: at least one ray source rotatable between at least two scanning positions around a rotation axis, and a rotation angle of at least one ray source between two adjacent scanning positions is greater than an angle of adjacent target spots of each ray source relative to the rotation axis; a detector assembly, and a conveying device configured to carry an object to be inspected. At least one ray source and the detector assembly are movable in a traveling direction relative to the conveying device, so that the object to be inspected may enter an inspection region. When at least one ray source is located at one scanning positions, at least one ray source and the detector assembly move in the traveling direction relative to the conveying device and at least one ray source emits X-rays; after moving a predetermined distance, at least one ray source rotates around the rotation axis to another scanning position.

Abstract: A radiographic inspection device and a method of inspecting an object are provided. The radiographic inspection device includes a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has a first opening connecting to an outside; a transfer mechanism applicable to carry the object and move through the inspection space; a shielding curtain mounted at the first opening; and a driving mechanism. The driving mechanism includes: a driver mounted on the support frame; and a joint portion, where an upper end of the shielding curtain is connected to the joint portion. The driver is configured to synchronously drive two ends of the joint portion, so that the shielding curtain moves up and down with the joint portion to open or close the first opening.

Abstract: Examples are directed toward systems and methods relating to security screening. For example, a screening system includes a sensor array to sense a gravitational field caused by an item, and a conveyor to convey the item through sensing positions for scanning by the sensor array. A controller acquires weight measurement information from sensor elements, and gravitational measurement information from the sensor array. The conveyor incrementally advances the item through additional sensing positions to acquire weight measurement information and gravitational measurement information. The controller performs tomographic reconstruction to generate a tomographic image of the item, using a generated weight map as a static weight input vector and using a generated mass map as a static mass input vector for the tomographic reconstruction.

Abstract: A sample inspection system contains a source of electromagnetic radiation and an apparatus that includes a beam former, a collimator and an energy resolving detector. The beam former is adapted to receive electromagnetic radiation from the source to provide a polygonal shell beam formed of at least three walls of electromagnetic radiation. The collimator has a plurality of channels adapted to receive diffracted or scattered radiation at an angle. The energy resolving detector is arranged to detect radiation diffracted or scattered by a sample upon incidence of the polygonal shell beam onto the sample and transmitted by the collimator.
