China Aerospace¹ Science and Industry Corp, the country's largest missile maker², developed what engineers say is the most advanced security screening instrument in the nation - the so-called 3D millimeter wave scanner.

 

中国航天科工集团研发出一款据工程师称是国内最先进的安检仪器——3D毫米波扫描仪。
 

 

The scanner, designed and built by the Beijing Huahang Radio Measurement Institute under CASIC's Third Academy, is the "smartest and most capable" of all security scanners in China, according to the institute, which specializes in radar³ and photoelectric⁴ equipment.

 

Several countries including the United States, the United Kingdom and Japan have already adopted similar wave scanners for airport security checks.

 

The device is a whole-body imaging device that uses a form of electromagnetic radiation to detect objects concealed⁵ beneath a person's clothing.

 

Zhao Yinghai, chief designer of the product, said that compared with the metal detectors⁶ widely employed at government buildings, public venues⁷ and security checkpoints at airports and railway stations, the new scanner offers faster response times and higher accuracy with much less manpower needed.

 

The scanner is capable of detecting as many as 89 dangerous or risky⁸ items within 1 second, including those "invisible" to existing body-screening devices such as corrosive⁹ or flammable liquids.
