WASHINGTON (CBSDC) – The Department of Homeland Security will soon be using a laser at airports that can detect everything about you from over 160-feet away.
Gizmodo reports a scanner that could read people at the molecular level has been invented. This laser-based scanner – which can be used 164-feet away — could read everything from a person’s adrenaline levels, to traces of gun powder on a person’s clothes, to illegal substances — and it can all be done without a physical search. It also could be used on multiple people at a time, eliminating random searches at airports.
The laser-based scanner is expected to be used in airports as soon as 2013, Gizmodo reports.
The scanner is called the Picosecond Programmable Laser. The device works by blasting its target with lasers which vibrate molecules that are then read by the machine that determine what substances a person has been exposed to. This could be Semtex explosives to the bacon and egg sandwich they had for breakfast that morning.
