Terminal 4

Terminal 4

Terminal 4 is a self-portrait of John Wild, produced using a Rapiscan Secure 1000 security scanner. The Scanner currently in use at Heathrow’s Terminal 4 creates security images of travelers through a process known as backscatter radiation. An image is produced by firing a low level of radiation at the traveler and analyzing the radiation that is bounced back. Radiation penetrates below the clothing and is reflected from the skin (or bones that are close to the surface) allowing a computer to generate an image of the bodies surface.
