Every day thousand of objects (luggage, bags, parcels, envelopes, etc.) are scanned in airports, post offices, railway stations and other buildings requiring a high level of security, to reveal the eventual presence of hidden explosives or similar dangerous substances. Unfortunately, conventional X-ray machines cannot reliably detect plastic explosives because such materials can be molded into various shapes and disguised as commonly packed travel items, which do not provoke the attention of the X-ray operator. These explosives also do not set off metal detectors. The aim of the present project is to develop a multi-technique control system able to detect, with a very high reliability, explosives hidden inside objects. This innovative system will combine two existing and already developed control techniques (a dual energy X-ray computer-aided tomography and a metal detector) with a suitably developed "electronic nose".
