Stansted Airport in Essex is to trial a new state-of-the-art body scanner.
Security staff will be able to see an outline image of passengers who have activated the walk-through security arches leading to departures. The image will show where the arch has detected any concealed items.
The airport says the new scanner will provide a less-intrusive method of security screening by reducing the need for pat-down searches. It also says that no images will be saved or be retrievable at a later date.
The trial will start on Thursday and is due to run for three months. Passengers who are selected for a scan will have to comply with the scans, or they will not be allowed to travel.
