IMS scanners boost security

Netherlands-based Eye on Air has developed two new ion mobility spectrometry (IMS) scanners for airport security.

The Air Brush shoe scanner will probably be deployed operationally in an inline system, according to mechanical engineer Jos Beers. It will initially be used to randomly sample passengers, although Air Brush would also meet the needs of all UK airports preparing for possible 100% shoe scanning at the checkpoint.

A prototype Air Brush was displayed at the International Security Expo in London in late November. The device has two parts: a monitor, on which results of the scan are displayed, and a floor level component that undertakes the scan. Passengers simply stand on two footprints. Here, the air around their shoes is sucked into an analyser, which compares the vapour with an explosives database within the machine. This process takes no more than six seconds.

“If the analysis is negative, a green light prompts passengers to complete the security screening process,” Beers told Jane’s .

Eye on Air also hopes to obtain European certification in 2019 for the Eyon1 explosives trace detector. “It is similar to equipment already in the market, but significantly cheaper to operate,” said Beers, who explained that Eye on Air uses aluminium rather than traditional glass or fabric swabs.
