Camera 'looks' through clothing

All objects emit terahertz radiation

A camera that can "see" explosives, drugs and weapons hidden under clothing from 25 metres has been invented.

The ThruVision system could be deployed at airports, railway stations or other public spaces. It is based on so-called "terahertz", or T-ray, technology, normally used by astronomers to study dying stars.

Although it is able to see through clothes it does not reveal "body detail" or subject people to "harmful radiation", according to the designers.

"It is totally and utterly passive - it receives only," said a spokesperson for Thruvision.

The portable camera, which has already been sold to the Dubai Mercantile Exchange and Canary Wharf in London, will be shown off at the Home Office scientific development branch's annual exhibition later this week.

Body glow
Unlike current security systems that use X-rays, the ThruVision system exploits terahertz rays, or T-rays. This electromagnetic radiation is a form of low level energy emitted by all people and objects.

These are able to pass through clothing, paper, ceramics and wood but are blocked by metal and water. The system works by collecting these waves and processing them to form an image which can reveal concealed objects.

"If I were to look at you in terahertz you would appear to glow like a light bulb and different objects glow less brightly or more brightly," said the firm's spokesperson.
"You see a silhouette of the form but you don't see surface anatomical effects."

In addition, the system does not involve any of the "harmful radiation associated with traditional X-ray security screening", according to the firm.
The company has made previous versions of the camera, but the T5000, as it is known, is the first that works both indoors and out.

The system exploits technology originally developed at the government owned Rutherford Appleton Laboratory (RAL) in Oxfordshire.

"Astronomers use T-ray cameras that can see through dust and clouds in space, revealing what lies beyond," explained Dr Liz Towns-Andrews, of the Science and Technology Facilities Council which runs RAL.

Other terahertz systems, developed by companies such as TeraView, are used to probe the structure of pharmaceutical compounds.

Although it is able to see through clothes it does not reveal "body detail" or subject people to "harmful radiation", according to the designers.

Sorry guys ... if you were thinking the other way round.

 

[Faun]

i knew that

 

[Voldy]

hehe nice news
btw when i first read the title i got exicted but soon as my read of article is over i came soon to my original state

 

[Ecko]

After starwars people taking ideads from BadShah

 

[ring_wraith]

Needless to say, the title had me thinking, "Finally!"

 

[naveen_reloaded]

old news buddy.. i have seen it before long time on discovery...

i was SSOOOOO excited .... well u all know wht ...

 

[fun2sh]

yep.its old news. i think it was on digit too. but it was some other form of technology.entirely different from this T-rays

 

[jithudigitised]

may be this can also see the body details..... it may be a hidden feature,we may have to crack it..hehehe

 

[gary4gar]

when can we see the body detail, i am sure its possible

 

[hullap]

^rofl :roll:

 

[x3060]

such a big hope i had . . after reading , all gone

 

[tech_lover]

early models of sony handycam with nightshot ON could see through a layer of clothing when used during the day. too bad someone complained and the company rectified it immediately.

 

[Quiz_Master]

Jeeg.. After reading I though we will be able to see clearly...
Maybe another 4-5 years..

(I hope they dont invent X-Ray proof cloths by then )

when can we see the body detail, i am sure its possible

LOL!
