Here’s some more information on new airport screening tech (LA Times).

The screening device, which is about the size of an old-fashioned PC computer tower and weighs about 50 pounds, reads the outline of people to reveal firearms and explosives hidden under their clothes.

Unlike the TSA’s existing full-body scanners that bounce millimeter waves off of passengers to spot objects hidden under their clothes, Gramer said, the passive terahertz technology reads the energy emitted by a person, similar to thermal imaging used in night-vision goggles…

As a result, Thruvision boasts that its technology can screen up to 2,000 people an hour and detect a concealed device at a distance of up to 25 feet. Initially, the system can be used in addition to the existing full-body scanners already deployed at airports, but Gramer said the device can eventually replace parts of the TSA’s security screening system.

I think anyone will welcome a more convenient flying experience at this point, but it is somewhat sinister to think of this technology being installed in all sorts of public places, work places, police cars, etc.
