Sense of security

摘要

Technology originally developed for space communication projects may soon be used by UK security forces to detect concealed weapons at airports or railway stations. The Tadar sensing system, which takes its name from the Brazilian Tadarida bat, is designed to detect metallic and non-metallic objects hidden beneath clothing. It uses 3mm-wavelength technology that can see through clothing, but is completely harmless to people, according to its Irish developer, Farran Technology.
