Because the terahertz wave signal radiated by the human body itself is extremely weak, the terahertz chip is required to have ultra-high sensitivity, ultra-low noise, and ultra-wideband characteristics in order to detect the weak signal of human radiation and achieve the purpose of imaging.
Wang Qiang, deputy director of China Electronics 13th, told reporters that this chip can detect the weak terahertz waves emitted by the body's own radiation and analyze the detected signals through the internal algorithm of the instrument to image the human body and help the security check. The personnel quickly investigate the dangerous goods carried by the human body, and at the same time it will not cause radiation hazards to the personnel to be inspected, providing an effective solution to the security problem.
In the past, the core imaging chip technology in the security instrument has been controlled abroad. Wang Qiang said that this terahertz chip has achieved independent research and development in key links such as material growth, process manufacturing, simulation modeling, and circuit design. Control. The use of these chips developed by the terahertz detector module, in terms of price and performance compared with similar foreign products have advantages, can replace the import, will significantly enhance the level of China's terahertz human security equipment, and promote the peaceful city of digital process.
