RESEARCH FUNDING FOR SAFER AND FASTER AIRPORT SCANNERS  

15 January 2020

Dr Okan Yurduseven from the Institute of Electronics, Communications and Information Technology (ECIT) at Queen’s has received a Leverhulme Award of £988,159 to develop a new era of airport screening scanners.

At present, security scanners are used at airports, train stations, tourist attractions and public buildings, and at events such as pop concerts, major sporting occasions and even schools.

Dr Yurduseven from ECIT has been awarded a Leverhulme Research Leadership Award to develop safer and faster technology which he hopes will cut the time it takes to collect and process data through security scanners from 10 seconds to less than a tenth of a second.

He explained: “When we arrive at the airport, everyone has to go through security clearance and body scanners which can take some time.

“When we walk through the scanner, it can take around 10 seconds to collect and process the data and reconstruct an image. It takes even more when the data is sent to a controller, who then manually checks it for illegal items. It can also add extra time when there are false alarms.

“While this may not sound like very long, we have to take into account the huge volume of people filtering through airport security every day and this causes huge queues.

“More worryingly is that the current system has been investigated and issues have been raised in terms of how many illegal items could go unnoticed.”

In 2015, an internal investigation of the Transportation Security Administration in the US revealed that undercover investigators were able to smuggle mock explosives or banned weapons through checkpoints in 95 percent of trials. Since then, Dr Yurduseven has been determined to develop a more effective solution that would also cut waiting times.

Speaking about the award, he said: “This Leverhulme Research Leadership Award will allow us to create technology that is fully electronic, rather than manually operated, and this will allow the scanners to process the images in real time – we think the entire scan process should be complete in less than a tenth of a second.

“By integrating machine learning into the design process, we will substantially reduce the false alarm rates in detecting threat objects. The outcome of this project will be of vital importance to ensure the safety of the public right across the globe.

“In order to do this we will use state-of-the-art millimetre-wave radar systems. We expect that the end result will be a much more effective system, leading to safer outcomes and reduced waiting times – so hopefully shorter queues at airports and other venues that use these scanners.”

Dr Yurduseven joined Queen’s as a Senior Lecturer (Associate Professor) in March 2019 from Duke University in North Carolina, USA, where he was a Postdoctoral Research Associate in the Department of Electrical and Computer Engineering.

He is now setting up a team to work on the five-year project and is searching for four talented PhD students and four postdoctoral research associates who will work on ground-breaking radar technology, image processing algorithms and deep learning schemes.

He added: “This is an amazing opportunity for myself and my team to carry out vital research using innovative engineering solutions to move science – and society – forward, all thanks to a Leverhulme Research Leadership Award.”

It is the first time that an academic at Queen’s University Belfast researcher has received a Leverhulme Research Leadership Award.
