New Passenger Security Technology Make Revolutionize Passenger Security Screens

A new technology from an Irish company may revolutionize aircraft passenger screenings and permit passengers to be scanned from 50 meters or so away.

Metal detectors currently used for screening aircraft passengers could soon be supplanted by novel millimetre-wave cameras, able to detect even non-metallic concealed objects. The new system, named after a Brazilian bat, is based on technology developed for ESA spacecraft. Tadar is being demonstrated at this week’s Inter Airport Europe Exhibition in conventional metal detectors, such as those used to check passengers at airports, are limited in that they can only detect metal objects. Other security technologies such as the X-ray imaging used to screen luggage, are unsuitable for checking people because of their use of ionizing radiation.
