Smile, camera, please!

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. 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. 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.
