摘要： The present disclosure provides a system and method for inspecting an aircraft. An X-ray/Gamma ray radiation source and a detector are located at above and below a fuselage of an aircraft, respectively. The X-ray/Gamma ray radiation source emits a beam of radiation[ ], wherein the X-ray/Gamma ray radiation[ ] passes through the aircraft to be inspected. The detector receives and converts the beam of X-ray/Gamma ray radiation[ ] that has passed through the aircraft to an output signal, and the system generates a vertical transmission image in real time.

摘要： The present disclosure discloses a radiation inspection system and a radiation inspection method. The radiation inspection system comprises a radiation source and a beam modulating device. The beam modulating device comprises a first collimating structure disposed at a beam exit side of the radiation source and a second collimating structure disposed at a beam exit side of the first collimating structure. The second collimating structure is movable relative to the first collimating structure to change a relative position of the first collimating port of the first collimating structure with the second collimating port of the second collimating structure, and the beam modulating device is shifted between a first operational state in which the beam modulating device modulates an initial beam into a fan beam, and a second operational state in which the beam modulating device modulates the initial beam into a pencil beam variable in position.

摘要： The present disclosure discloses an alignment system and an alignment method for a container or vehicle inspection system, and an inspection system. The inspection system comprises comprising an ray source, a collimator, a detector arm and a detector module mounted on a detector arm, the ray source, the collimator and the detector module are arranged to form an inspection passage, a ray beam emitted from the ray source passes through collimator and irradiates onto an inspected object, and an attenuated ray beam is collected by the detector module so as to complete inspection. The alignment system comprises a measuring module arranged to receive the ray beam emitted from the collimator and to measure the ray beam so as to determine positions and orientations of the ray source and the collimator. With the alignment method, alignment between a center point of the ray source, a central line of a detector tip and a central line of the collimator may be more accurately measured.
