The US Department of Homeland Security has provided researchers from Nottingham Trent University with $4.4 million to develop an airport security system which uses scattered X-rays to identify the unique chemical signatures of materials.
This technology could allow for far more accurate identification of materials than conventional airport scanners. Professor Paul Evans, head of the Imaging Science Group at Nottingham Trent University, said: “This system has the potential to revolutionise airport security scanning – for the first time we can accurately identify materials via their molecular fingerprint.”
