Team at Nottingham Trent University Create New X-Ray Scanning Technology for Airport Security
A research team at Nottingham Trent University lead by Professor Paul Evans have developed a new x-ray scanning method, which will mean fewer false alarms at airports all over the world.
The new improved method developed will help to detect concealed weapons and explosives by using a single x-ray source to produce divergent beams, which capture different views of objects under inspection simultaneously, providing more information about the object’s shape and depth.
Professor Evans confirms that "Using 3D techniques employing colour X-ray sensors enables a range of different materials to be detected as well their shape and position inside a bag. The number of people needed to carry out the detection may also be reduced.
"The project is ongoing, and we're currently working on how to make the equipment smaller and more cost-effective. But our divergent beam technology is now the de facto standard in the industry."
The new technology has already been implemented at over 4,500 airports around the globe, helping the on-going battle of protecting the public from potential terrorist threats. Professor Evans advises that the technology is years in the making and his research dates back to the 1990s, when the Home Office was investigating airport security in response to the Lockerbie bombings.
The technology has made such an impact that the work was recognised by the Queen’s Anniversary Prize, awarded at Buckingham Palace in February.
