Liberty Defense Holdings’ millimetre-wave shoe screening technology has won the 2022 Interagency Partnership Award from the Federal Laboratory Consortium for Technology Transfer.

The technology, which was developed at Pacific Northwest National Laboratory (PNNL) and exclusively licensed to Liberty for commercialisation, is intended to eliminate the need for passengers to remove their shoes during airport security checks. It was developed in partnership with the US Department of Homeland Security, Science and Technology Directorate

"This is a great accomplishment and a true reflection of the partnership between PNNL and Liberty to bring innovative and next generation security technology to the market," said Bill Frain, CEO of Liberty Defense. "The shoe screening technology, paired with the High-Definition Advanced Imaging Technology body scanner, also licensed to Liberty, will revolutionise screening at aviation checkpoints."

The millimetre-wave shoe scanner uses advanced imaging to detect concealed objects in footwear.

"In practice, the shoe screener could be integrated into the floor of the existing airport body scanning portals or be used as a standalone unit at the checkpoint," added Frain. "Our goal is to improve not only the efficacy of airport screening, but also improve the experience of passengers. This technology has the potential to do just that."
