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.

that ad including the word “illusory” back when I was reading
comics ;-) .
