Britain makes camera that "sees" under
clothes
LONDON (Reuters) - A British company has
developed a camera that can detect weapons,
drugs or explosives hidden under people's
clothes from up to 25 meters away in what could
be a breakthrough for the security industry.
The T5000 camera, created by a company called
ThruVision, uses what it calls "passive imaging
technology" to identify objects by the natural
electromagnetic rays -- known as Terahertz or
T-rays -- that they emit.
The high-powered camera can detect hidden
objects from up to 80 feet away and is effective
even when people are moving. It does not reveal
physical body details and the screening is
harmless, the company says.
The technology, which has military and civilian
applications and could be used in crowded
airports, shopping malls or sporting events, will
be unveiled at a scientific development exhibition
sponsored by Britain's Home Office on March
12-13.

"Acts of terrorism have shaken the world in recent years and security precautions have been
tightened globally," said Clive Beattie, the chief executive of ThruVision.
"The ability to see both metallic and non-metallic items on people out to 25 meters is
certainly a key capability that will enhance any comprehensive security system." While the
technology may enhance detection, it may also increase concerns that Britain is becoming a
surveillance society, with hundreds of thousands of closed-circuit television cameras already
monitoring people countrywide every day. ThruVision came up with the technology for the
T5000 in collaboration with the European Space Agency and from studying research by
astronomers into dying stars.
The technology works on the basis that all people and objects emit low levels of
electromagnetic radiation. Terahertz rays lie somewhere between infrared and microwaves
on the electromagnetic spectrum and travel through clouds and walls. Depending on the
material, the signature of the wave is different, so that explosives can be distinguished from a
block of clay and cocaine is different from a bag of flour.
