Abstract
A baggage inspection device based on coherent x-ray scatter has an x-ray source on one side of the scanning area and detectors on the other side of the scanning area. The detectors measure the energy of the scattered x-ray quanta. A primary ray collimator is arranged between scanning area and x-ray source. A secondary ray collimator for scattered rays is arranged between scanning area and detectors. The detectors are positioned on a Z axis forming an axis of symmetry for the secondary ray collimator. A point 0 on the Z axis forms the origin of a Cartesian coordinate system. The primary ray collimator allows passage only of x-ray beams impinging on the point 0. The x-ray source has an extended anode with a focus position controlled electronically about the anode length. Primary ray collimator and x-ray source extend cylindrically symmetrically about the symmetry axis or parallel to the Y axis in the X-Y plane.
