Brijot Imaging Systems, Orlando, FL, has introduced the BIS-WDS® GEN 2 object detection and people screening system that provides security officials with an effective method of detecting and locating suspicious objects on a person quickly and discretely. The system features full-motion, real-time passive millimeter-wave imaging that allows users to search for potential threats on an individual from a standoff distance while the person walks through the system’s field of view. It also detects liquids and gels hidden beneath a person’s clothing, as well as objects made of metal, plastic, composite, liquid, and other materials that contrast with the millimeter-wave energy naturally emitted by the human body.

The BIS-WDS GEN 2’s sensors do not image anatomical details or emit radiation. The system can begin imaging hidden objects when a subject is about 15 feet from the millimeter sensor aperture with an optimal focal distance of 10 feet. The system continually looks for millimeter- wave contrast and detects items based on selected size settings, with the minimum definable size of 2.5 × 2.5". The automated detection engine is comprised of three images: the real-time CCD camera image, the raw millimeter-wave image, and the processed millimeter-wave image. A graphical user interface displays up to three detection items at a time, identifying detection events in real time as they occur.
