waves could one day enhance airport security by detecting dangerous items from dozens of feet away, according to a university study.
Jingle Liu, one of the co-authors of the paper, noted that ordinarily, generating terahertz
waves with electronics is a problem because they need to be cooled.
imaging with a multiple sensor platform technology, TeraView has shown that terahertz
light has the potential to quickly, accurately and non destructively measure tablet features, such as tablet integrity or, coating thickness and density, while the tablets are in a state of fast and random motion as found on a tablet compression machine.
The detective team that went to France carried a device that emits terahertz
Durham Photonics has benefited from Cenamps' BioNano Regional Research Programme, which funded research in the Photonics Materials Institute that underpinned the terahertz
waves are similar to microwaves and x-rays because they can pass through certain materials without harmful affects.
radiation has been used in the detection of concealed weapons, explosives and drugs as it has the ability to penetrate a variety of materials such as clothing, paper, cardboard, wood, masonry, plastics and ceramics.
He said: "Different molecules absorb and reflect terahertz
waves in a recognisable way.
In the longer term, Phiar will partner with technology companies to develop applications for its terahertz
Police minister Hazel Blears said: "Although the full potential of terahertz
technology is not likely to be realised for several years, some capability may be available in the shorter term.
spectroscopy has only become possible with the development of appropriate sources and detectors of terahertz
radiation, which has accelerated over the past five years.
The two companies will co-develop a next-generation hand-held security wand that utilises terahertz
light waves to detect and identify metallic and nonmetallic weapons, as well as bulk and sheet explosives that are concealed beneath clothing, inside shoes, or in other objects.
