Johnny See-All

If the invisibility cloak wasn't amazing enough, here's a tool to actually see through clothes - Terahertz technology! Apparently using radiation in the terahertz region(frequency of one trillion times per second), it is possible to penetrate clothes and view objects next to the body, or the body itself. Due to the obvious privacy concerns, a British company Teraview has developed technology that allows security staff to use a handheld wand to scan people. Instead of showing an image on screen, it uses the signature of the reflected radiation to detect weapons or drugs. Interesting, but since the technology exists, will there be t-ray goggles in the future?
