Abstract: Since 9/11, there has been a growing interest to improve the security both of air travel and of cargo shipping. Visual inspection is the simplest tool and is very efficient when single objects of small size are to be checked. The complexity of inspection increases when we have large |boxes| and/or when several objects are packed into a closed space, as in luggage or even in larger volumes like shipping containers or trucks. This paper gives a brief overview of how different X-ray techniques are used for fast checking of small and large objects.

Keywords: homeland security; X-ray measurements; X-ray imaging; X-ray radiology; imaging detectors; flat-panel imaging arrays; air travel; cargo shipping; fast checking; X-ray inspection; small objects; large objects.
