The QPS security scanner delivers high-precision and efficient security control while ensuring an unobtrusive and uncomplicated experience for scanned persons. It consists of a flat panel with thousands of transmitters that emit extremely low-powder millimeter waves in very short succession and just as many receivers that record high resolution 3D information. The QPS is designed for implicit privacy. Rather than generating photographic images, it evaluates physical information. Detected locations of interest are marked on a symbolic body graphic.
