近日,民航局颁布相关标准及程序文件,正式将毫米波人体成像设备纳入中国民航安检设备清单。 毫米波人体成像设备将正式用于机场安检 An exhibitor demonstrates a security scanner that uses millimeter wave imaging at a science and technology convention in Xi'an, Shaanxi province, last year. The technology was introduced recently for use in civil aviation in China.Zhang Yuan / China News Service Using a technology known as millimeter wave imaging, the security scanner can detect objects hidden under clothing, including nonmetallic objects, and can show their shape, size and position, the administration said. 民航局表示,使用毫米波人体成像技术进行安检可以检测出在衣物覆盖下藏匿的物品,包括非金属物品,并可以从图像上获取隐匿物品的形状、大小和位置等信息。 毫米波人体成像技术(millimeter wave imaging)是目前全球安防领域的先进技术,已在美国、英国、荷兰、澳大利亚、日本等国机场用于旅客人身安检。这是安检中常用的一种全身扫描(full body scanner)设备,具有对人体无害、穿透力强的特点,其发射功率不及手机电磁波辐射的千分之一(an emission strength less than 1-thousandth the electromagnetic radiation of a mobile phone),能准确识别人体携带物品,有效提高检查的客观性、准确性、针对性,降低安检员的劳动强度,提升安检效率。 民航局称,未来,毫米波人体成像设备将逐步取代民用机场沿用26年的金属探测门(walk-through metal detectors),旅客也将体验到更加安全、高效的人身安检服务。 【相关词汇】 面部识别 facial recognition 指纹识别 fingerprint verification 静脉验证 finger vein verification 金属探测器 metal detector 电子监控 electronic monitoring system 嗅探犬 sniffer dogs (中国日报网英语点津 马文英)
