Abstract
Disclosed is a detector array comprising a first linear array for detecting a first ray and a second ray which penetrate through a first plurality of parts of the inspected object to acquire first values and second values for the first plurality of parts, wherein the second ray is alternately emitted with the first ray; and a second linear array arranged parallel to the first linear array for detecting the first ray and the second ray which penetrate through a second plurality of parts of the inspected object to acquire third values and fourth values for the second plurality of parts, wherein the first plurality of parts is partly identical to the second plurality of parts. With the detector array, the efficiency and material discrimination accuracy can be improved in the scanning inspection of the inspected object by use of alternate dual-energy rays.
