A device for inspecting contraband in an aviation cargo containers includes: a turntable located at an object inspecting position and configured to carry the object to be inspected and bring the object into rotation; an object conveying system; a scanning system including a radiation source and a detector which can synchronously move in the vertical direction; a turntable drive/control system which drives and controls rotation of said turntable so that the turntable can continuously rotate about its rotation axis or rotate to any predetermined angular position; a scanning drive/control system which drives and controls the radiation source and the detector into synchronous movement in the vertical direction so that the radiation source and the detector can continuously move in the vertical direction or move to any predetermined vertical position. The device of the present invention can scan the object and form images in various scanning modes to meet different needs.
