A Camera with T-ray Vision

A camera that is sophisticated enough to tell if you have sugar in your pocket, not cocaine from a distance of 40ft., but doesn’t see your naughty bits could find a home at security points in airports or at borders throughout the globe.
At least that’s what ThruVision, the company developing the T5000 camera hopes. The camera sees objects that emit Terahertz, or T-rays, which pretty much includes all people and most objects. 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 company claims.
Every material emits a different signature of Terahertz wave, which lies between infrared and microwaves on the electromagnetic spectrum. That means it can tell the difference between cocaine and sugar the company said. 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.
