New technology that can “see” through clothing and detect what’s underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places.
The ThruVision T5000 camera picks up 1)Terahertz rays, or T-rays, which are naturally emitted by all objects and can pass through fabric or even walls.
The camera can then detect metallic and non-metallic objects hidden under clothing on still or moving subjects without 2)revealing any body detail, according to its British manufacturer, ThruVision Limited.
While similar technology is being unveiled at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding 3)bottlenecks at border crossings or security 4)checkpoints.
It also means people can be screened without
knowing it.
Amid privacy concerns, ThruVision Chief Executive Clive Beattie said the image produced by the camera did not reveal detailed 5)anatomy.
“It’s almost a glowing light bulb,” Beattie said. “You don’t see the detail that people might be concerned about.”
Explosives, liquids, 6)narcotics, weapons, plastics, and 7)ceramics can all be detected by the camera’s
imaging technology, which the company says is
completely safe. Unlike X-rays, the T5000 does not emit radiation – it only picks up on it.
The technology 8)stems from British astronomers’ work in studying dying stars. Astronomers use T-ray cameras to see through dust and clouds in space.
The company sees uses for its camera at 9)high-profile sites like political or business 10)venues, and outdoor areas like tourist attractions and sports
11)arenas.
The camera is already in use in London’s Canary Wharf financial area.
In London’s busy Piccadilly Circus – which is already filled with closed-circuit 12)surveillance cameras – reaction to the new technology was mixed.
Some said the camera was going too far and invading privacy, but others said they are willing to put safety before privacy concerns.
“There’s surveillance everywhere anyway,” said one 13)commuter. “I don’t think it’s much of a difference. I don’t care that they can see through me, because they can see me anyway.”
Some experts said the intrusion of the camera was not worth the benefit.
“What we should consider is how much we want to lose aspects of our privacy in order to attain a sort of national security,” said David Murakami Wood, director of the Surveillance Studies Network, which deals with surveillance and privacy issues. “In most cases this isn’t real security – it’s a sense of safety that has very little real effect.”
一种能够透视衣服并检验衣服之下隐藏物的新技术如今可以用来扫描人群。它可能成为阻止恐怖袭击在公共场所发生的有效工具。
这种ThruVision T5000摄像头能接收太拉赫（万亿赫兹级）射线——即T射线。所有物体在自然状态下都可以发出这种射线，它可以穿透织物甚至墙体。
据此产品的英国制造商ThruVision公司称，这种摄像头可以在静止或移动状态下监测出监控对象隐藏在衣物下的金属或非金属物品，而不会揭露任何身体细节信息。
尽管类似的技术已运用于世界各地的机场，但这款T5000专为大片开阔区域而设。其监控范围达25米，可以在公共场所对人群进行检测，从而避免了在出入境关口或者
安全检查点的拥堵问题。
这也意味着人们可能在毫不知情的情况下被检查。
当问到对隐私问题的担忧时，ThruVision总裁克力夫·贝蒂说，这种摄像头产生的图象并不会显现详细的人体特征。
“它几乎就是一个发光的灯泡，”贝蒂说道，“你看不到人们可能有所担忧的身体
细节。”
这款摄像头的成像技术可对爆炸物、液体、麻醉品、武器、塑料制品和陶瓷制品进行探测。该公司说此技术十分安全。与X射线不同，这款T5000不会产生辐射——它只
接收射线。
这项技术（的灵感）源于英国天文学家对陨星的研究。天文学家们使用T射线摄像机，
透过宇宙中的重重星尘和星云进行观测。
该公司看到了此款摄像头的商业潜力在于用于人群出入较多的场所——如政治或商业性地段，还有如旅游名胜或体育竞技场等户外
区域等。
这款摄像头已经在伦敦的金融区“金丝雀码头”投入使用。
伦敦繁华的皮卡迪里广场已经布满了闭路监控摄像头，人们对这种新技术的反应则毁誉参半。
有人说这款摄像头的设计太过分，侵犯了人们的隐私权；也有人愿意把对隐私问题的考虑放在安全因素之后。
“不管怎样，监控设施无所不在，”一位上班族说。“我认为这不会有什么差别。我不在乎他们（是否）能透视我，因为不管怎样，他们都能看到我。”
一些专家则表示，采用这些摄像头得不偿失。
“我们应该考虑的是，我们在方方面面要牺牲多大的隐私去换取一定程度的国家安全，”“监控研究网”的总监戴维·木拉卡米·伍德说，其公司主要处理监控和隐私方面的问题。“在大多数情况下，这种安全并不是真正的安全——它只是一种安全感，而这几乎是于事无补的。”
