    Abstract: An inspection system and method, and the system includes: a ray source; a detector assembly; and a conveying device for carrying an aviation pallet cargo. The ray source and the detector assembly are movable in a traveling direction parallel to the central axis relative to the conveying device so that the aviation pallet cargo enters an inspection region, the ray source is translatable between a plurality of scanning positions, and a translation distance of the ray source between two adjacent scanning positions is greater than a spacing between adjacent target spots of the ray source. When the ray source is located at one of the scanning positions, the ray source and the detector assembly move in the traveling direction and the ray source emits X-rays; and when the ray source and the detector assembly move a predetermined distance in the traveling direction, the ray source translates to another one of the plurality of scanning positions.

    Abstract: Provided are an inspection system and an inspection method, the inspection system includes: a carrying device (300); at least one ray source (100) each includes a separate housing (110) to define a vacuum space and target spots enclosed within the housing (110), and a detector assembly (200). The at least one ray source (100) is rotatable between a plurality of scanning positions around a rotation axis relative to the carrying device (300). The at least one ray source (100) and the detector assembly (200) may be lifted or lowered along the rotation axis relative to the carrying device (300). When the at least one ray source (100) is located at one of scanning positions relative to the carrying device (300), the at least one ray source (100) and the detector assembly (200) are lifted or lowered along the rotation axis relative to the carrying device (300) and the at least one ray source (100) emits X-rays. After the at least one ray source (100) and the detector assembly (200) are lifted or lowered a predetermined distance relative to the carrying device (300), the at least one ray source (100) rotates around the rotation axis relative to the carrying device (300) to another one of scanning positions.

    Abstract: An inspection system and method, the inspection system includes: a carrying device, at least one ray source and a detector assembly. The ray source and the detector assembly are lifted or lowered along a central axis of the carrying device relative to the carrying device. When viewed along the central axis, the ray source is translatable between scanning positions relative to the carrying device. When the ray source is at one of the scanning positions the ray source and the detector assembly are lifted or lowered relative to the carrying device along the central axis, and the ray source emits X-rays; and when the ray source and the detector assembly are lifted or lowered a predetermined distance the ray source translates to another scanning position. The inspection system further reconstructs a three-dimensional scanning image of the object to be inspected based on detection data of the detector assembly.
