Colour 3D X-ray Imaging for Security Screening

The university team has previously developed an X-ray imaging technique that combines binocular stereoscopic imagery with motion or kinetic depth effects (KDE). The technique is designed to enhance the screening of X-ray luggage at airport checkpoints. This paper presents initial investigations concerning the production of dual-energy X-ray (materials discriminated) multiple view sequences. The colour line-scan format images are produced by a novel image intensified X-ray system. This work is part of an ongoing collaborative research programme with the UK Home Office Scientific Development Branch (HOSDB) and US Department of Homeland Security (DHS) to develop and evaluate KDE X-ray technology.
