Scan while moving
The Sequestim walk-through scanner uses space technology to image human body heat.
Computer learning allows the scanner to distinguish between threats and non-threats but without the need for passengers to keep still or remove outer clothing.
The scanner combines a number of world-leading technologies developed in Cardiff.
See hidden objects
The human body acts as a source of “light” by which the new scanner can see hidden objects which appear as a shadow.
This is in contrast with existing scanners which process reflected and scattered radiation from a source within the machine.
