A sensor that can scan huge crowds and pick out a lone suicide bomber by homing in on hidden explosives has undergone official tests, The Sun reported Thursday.
The revolutionary gadget — similar to airport scanners but top secret — is believed to silently analyze materials using the unique “terahertz” waves emitted by different substances.
British government scientists began testing it a year ago on mock crowds where one person in every 75 carried a “Person-Borne Improvised Explosive Device.”
