From Michael Bane, I find this lovely link:
LONDON (Reuters) – A British company has developed a camera that can detect weapons, drugs or explosives hidden under people’s clothes from up to 25 meters away in what could be a breakthrough for the security industry.
The T5000 camera, created by a company called ThruVision, uses what it calls “passive imaging technology” to identify objects by the natural electromagnetic rays — known as Terahertz or T-rays — that they emit.
They say that the camera doesn’t “reveal body details” and that the scans are harmless. I guess they’re worried about pervy people looking through you clothes while they’re invading your privacy. With the way technology is advancing, it should does make totalitarianism a lot easier.
Now, I can actually see a legitimate use for this kind of technology, you could use it to screen people entering secured areas, and it would be a lot more efficient than the current method they use at airports. I could actually leave my clothes on instead of having to get half naked and then have some GED graduate hassle me about a bottle of vitamins in my carry-on. But I digress, because I know that these won’t get used just for screening at secure checkpoints.
I can hope that the American’s traditional resistance to invasions of privacy like this would kick in and prevent these from ever crossing the pond.
