The MWS is a handheld, image-free, battery-powered, passive millimeter wave people screening device that detects both metallic and non-metallic objects. It is also an alternative to physical pat-downs by providing a high-level of object detection without making any contact with the person's body. All surfaces of a person can be scanned without contact-including the hair, top of head, chest, arms, sides, groin area, legs, and ankles.
