HELPING AIRPORT SECURITY?

International airports across the world could soon be using X-ray vision technology that was designed by staff and students at Stellenbosch University's department of electrical and electronic engineering. The Scryer Imaging Device last year won third prize at the annual Innovation Fund Competition. It was developed by Retief Gerber, a post-graduate student and lecturer, who was assisted by Dr Coenrad Fourie, and another post-graduate student, Dave Northeast. The concept works on the principle of reading frequencies emitted by different objects. The device detects hidden objects on a person such as metal, plastics or ceramics, and can is able to screen people as they stand in queues. Gerber, Fourie and the university will be the joint holders of the patent.
