China introduces millimeter wave tech into airport security checks

China has officially introduced a human imaging device with millimeter wave technology into its airports' security checks, according to the country’s civil aviation authorities.

The Civil Aviation Administration of China (CAAC) issued its latest official technical standards and testing program for the millimeter wave human-imaging technology used for airport security checks.

Following the US and EU, China is the first in Asia to issue the related technical admission standards, though several countries include the US, Britain, the Netherlands, Australia and Japan have already put that tech in use.

The new technology will gradually replace current metal detectors, which have been in Chinese airports for 26 years, according to CAAC.

The millimeter wave human-imaging technology is the most advanced technology for global security checks, helping improve efficiency.

The technology is harmless to the human body but still has a strong imaging capacity. It can detect hidden objects found on a person no matter the size or location, even non-metallic ones.

Chinese civil aviation authorities began trial tests of the technology in four airports in August 2017.
