China has officially introduced a human imaging device with millimeter wave technology into its airports security checks. The millimeter wave human-imaging technology is the most advanced technology for global security checks, helping improve airport efficiency. The technology is harmless to the human body and has a strong imaging capacity. It can detect hidden objects found on a person no matter the size or location, even non-metallic ones.
The new-tech is used in airport security checks in several countries such as the United States, Britain, Netherlands, Australia and Japan. Chinese civil aviation authorities began trial tests of the technology in four airports in August 2017. Following the United States and the European Union, China is the first in Asia to issue the related technical admission standards. The new technology will gradually replace current metal detectors, which have been in Chinese airports for 26 years, according to CAAC
