Airport security scanner relies on same tech used to view the outer universe

Sequestim airport security scanner

The next generation of security scanners passengers may see at the world’s airports rely on the same technology that is used to see the most distant objects in the universe. 

Developed by researchers at Cardiff University the Sequestim scanner uses space technology to detect hidden objects. 

By detecting heat from the human body, which acts as a light bulb, it can easily find and identify concealed items, even through heavy clothing. 

The developers believe a walkthrough security scanner using its technology would cut airport passenger queues significantly while increasing security.  

Unlike the body scanners now in use at airports, no radiation is shone at the passenger, and security staff do not need to constantly view images as passengers pass.  

The team at Cardiff University and Sequestim are currently seeking to raise investment and a series of demonstrations will be taking place in August 2023.  

“Walk-through security screening is the Holy Grail for the aviation industry. Passenger numbers have risen incredibly fast post-pandemic. The International Civil Aviation Organisation – a UN specialized agency – predicts that by the end of 2023, numbers of travellers on most routes will have grown beyond peak passenger numbers in 2019. Following a four-year cycle of investment, refinement and technological advance, Sequestim has a product that will impact the global security market. It is now ready for private equity investment,” Ken Wood, CEO, Sequestim, said. 

Wood added: “By embracing AI, the scanner can learn to recognise threats. With passenger numbers expected to double in 20 years, Sequestim can cut waiting times and revolutionise the security experience, giving travellers more time to enjoy airport shops and restaurants. At the same time, we will empower security to keep people safe.” 

The company, which is 20% owned by Cardiff University, has worked closely with Rapiscan Systems, which manufactures security equipment and systems designed for checkpoints, cargo, vehicle, baggage, parcel, and air cargo security inspection. 

“A walkthrough body screening system that can meet the high standards of the European Civil Aviation Conference and the USA’s Transportation Security Administration in real time would revolutionise aviation security. Sequestim’s high resolution imaging and ability to discriminate a range of items and materials shows significant potential for people screening applications,” Ken Mann, CTO, Rapiscan Systems, said.
