In 2024, TSA screened three million people in a single day for the very first time. With unprecedented numbers of travelers passing through airports, S&T is focused on improving the airport experience of the future so passengers can move to their destinations with ease. New and retrofitted passenger screening systems are currently being tested at S&T’s Transportation Security Laboratory (TSL) in Atlantic City, New Jersey. The S&T Screening at Speed Program, in collaboration with TSA, is developing new concepts and technologies to help the Department of Homeland Security (DHS) meet the needs of passengers while also fine-tuning detection performance, so TSA continues to stay ahead of evolving threats and keep the traveling public safe. High Definition-Advanced Imaging Technology (HD-AIT) is the backbone of this development.  Passenger Screening: Reimagining Imaging At The Airport
