UK based ThruVision introduces the T5000 security camera system that can "see" explosives, liquids, narcotics, weapons, plastics, and ceramics hidden under clothing from 25 meters.

ThruVision’s passive imaging technology stems from a collaborative European Space Agency (ESA) project which was based on original research carried out over many years by UK astronomers, including those at the STFC Rutherford Appleton Laboratory to study dying stars.
The T5000 operates in the terahertz region of the electromagnetic spectrum – frequently this region of the spectrum is referred to with terms such as Terahertz rays, or T-rays. The T5000 is compact, rugged, portable, easy-to-use and completely safe.

T-rays are a form of low level energy naturally emitted from all materials, including rocks, plants, animals, and people. They can pass through smoke, clouds and many solid materials like clothing, and in some cases, even walls.
The T5000 passively collects these naturally occurring T-rays and processes them to form images that reveal concealed objects hidden under a person’s clothing without displaying physical body detail and without subjecting them to any of the harmful radiation associated with traditional X-ray security screening.

ThruVision Ltd. will show the T5000 at the Home Office Scientific Development Branch (HOSDB) Exhibition on March 12th & 13th 2008.
