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.
