Advanced sensing technology identifies security threats 25 metres before they even enter the arena

(03/10/2008)

London 2012 has put security of sporting arenas – traditionally difficult to monitor – in the spotlight. Advanced sensing technology is now being installed to stop security threats 25 metres before they even enter the arena.

“With the 2012 London Olympics approaching, the need for advanced security measures in sporting arenas has never been more critical – and this is where sensing technology delivers. The sensing experts across our network have produced a range of state-of-the-art sensors, many of which are being used by security agencies to mitigate terrorist attacks,” says Phil Cooper, Director of the Sensing & Instrumentation Knowledge Transfer Network (KTN).

ThruVision Ltd is now deploying passive security screening products that display images of objects concealed under clothing from a distance.

Unlike X-ray systems, ThruVision’s products are totally passive. ThruVision’s sensors collect terahertz waves (low-energy waves, naturally produced by people and objects) to provide non-intrusive real-time images of concealed objects. Moreover, ThruVision products present no privacy issues as body detail is not revealed.

“ThruVision’s products offer security staff the ability to passively screen people at various stand-off distances for concealed objects, thus giving them precious time to react accordingly. This, coupled with the non-invasive nature of our products enables ThruVision systems to be deployed in many different entrance screening scenarios” says Jonathan James, ThruVision Ltd’s Director of Product Marketing.

The novel terahertz security imaging technology forms images of threat or contraband objects – metallic and non-metallic – hidden under clothing from 25m away. This means a threat can be unobtrusively detected and identified well before it enters a sporting arena.

ThruVision’s passive imaging technology forms images of concealed explosives, liquids, weapons, plastics, ceramics, and narcotics, regardless of whether the subject is still or moving.

The sensor works by passively collecting terahertz waves that are processed to form images that reveal concealed objects under clothing.

This technology has been used at various entrance security screening locations, including the America’s Cup held in Spain.
