coondoggie writes "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. 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. It is unclear if the T-ray technology will generate the same sort of privacy concerns other advanced X-ray products have in the past.
