Brijot Imaging Systems has received a 20-month, $3.7 million contract from the Air Force Material Command to develop and deliver a prototype Long-Range Personnel Imager (LORPI) that could detect anomalies such as weapons and potential explosives hidden beneath a person’s clothing at stand-off ranges up to 100 meters. The contract is the first development award Brijot has received from the Defense Department. The contract is being funded by the Joint Improvised Explosive Defeat Organization. The LORPI, which will be a terahertz imaging system, could be placed on top of a building to monitor people as they approach a crowded square or for perimeter security at a military base, Robert Daly, Brijot’s chief technology officer, tells TR2. Even in large crowds it would be pretty obvious to tell if someone is wearing a suicide vest, he says. The terahertz technology will also provide a good image in poor weather such as fog or rain, Daly adds. Brijot is better known for its millimeter wave imaging technology, the Gen 2 stand off detection system which is used by the U.S. military, international and commercial customers. So far Brijot has modeled the LORPI in a three dimensional computer aided design, Daly says.
