Millimeter wave active human body security scanner is a high-tech device that uses millimeter wave technology for non-invasive security checks. It works by emitting extremely low-energy millimeter wave signals to the subject and receiving their reflected echoes. These reflected signals are processed by precise algorithms to generate an anonymous, facial featureless 3D human contour map on a computer, rather than a real image. The core advantage of this system lies in its ability to automatically identify various suspicious items attached to the surface of the human body, including traditional metal weapons as well as non-metallic prohibited items such as plastic explosives, ceramic knives, liquids, etc., and directly mark the risk location on the cartoon doll image, thereby guiding security personnel to conduct targeted inspections.
The entire process only takes a few seconds and does not require physical contact. While significantly improving security inspection efficiency and detection capabilities, it also focuses on protecting personal privacy and the experience of being inspected. The millimeter wave energy emitted by it is extremely low and widely considered safe for public health. Therefore, this technology has become an important choice to replace traditional security check methods in high standard security check occasions such as airports and important venues around the world, and plays a key role in the modern public safety system.
