Abstract: Provided are an inspection method, and an inspection system including: at least one ray source; a detector assembly and a conveying device. At least one ray source and the detector assembly may move in a traveling direction relative to the conveying device, so that the to-be-inspected object may enter an inspection region. When viewed along a central axis of the inspection region, at least one ray source may translate between scanning positions, and a translation distance of at least one ray source between two adjacent scanning positions is greater than a spacing between adjacent target spots of each ray source. When at least one ray source is located at one scanning position, at least one ray source and the detector assembly move in the traveling direction and at least one ray source emits X-rays. After moving a predetermined distance, at least one ray source translates to another scanning position.

Abstract: An inspection system and method, the system includes: a ray source rotatable between at least two scanning positions around a rotation axis, a rotation angle of the ray source between two adjacent scanning positions being greater than an angle of adjacent target spots of the ray source relative to the rotation axis; a detector assembly; and a conveying device for carrying an object. The ray source and the detector assembly are movable in a traveling direction relative to the conveying device so that the object enters an inspection region. When the ray source is 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 rotates around the rotation axis to another one of the scanning positions.

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.
