     The 'ghost cape' that could make fighter jets look like passenger planes
     “幻影斗篷”能讓戰(zhàn)斗機看起來像客機。
     Groundbreaking technology can make an object appear to be something else
     突破性技術,使物體看上去是別的東西
     Technology could be used to make a jet fighter appear to be a passenger
    plane, or a soldier appear to be a tree
     該技術可以使噴氣式戰(zhàn)斗機擁有客機的外形,或者讓一個士兵外形像棵樹。
    騰訊科學訊(Everett/編譯)據(jù)國外媒體報道,近日來自中國的研究人員提出了一種神奇的隱形裝置,可以使得一個物體看上去像另一種物體的特征。由南京東南大學的研究團隊使用相關技術構建了一個很簡單的隱形裝置,其特點在于不會將物體完全隱形,而是使之在表征上與別的東西類似,酷似一種新式的“幽靈斗篷”。該技術將入射光線散射,形成了兩個“幽靈”圖像,將真實的物體進行了偽裝。
    研究人員認為這項技術可以應用于噴氣式戰(zhàn)斗機,使之看上去像是一架客機,如果應用于單兵戰(zhàn)場特征防護,則該士兵看上去就像是一棵樹。新型光學隱形技術原理遠比傳統(tǒng)的“隱身”技術更加簡單。比如,由洛克希德・馬丁公司研制的 X-35系列隱身戰(zhàn)機使用傳統(tǒng)的外形隱形來達到減少雷達反射面積,在雷達圖像上就如同一只小鳥,或者根本沒有信號,如果這類第五代隱形戰(zhàn)機采用了新的隱形技術,那么它看上去則像是一架客機,同樣也達到了“隱形”的目的。
    新型偽裝技術可以在國防安全等領域進行應用,研究團隊已經(jīng)建造了一個原型機來驗證他們的理論,依靠新型偽裝屏蔽裝置,原來物體的外形等特征可以被改變,在某種程度上可以認為是一種具有錯覺產(chǎn)生功能的新型設備。實現(xiàn)偽裝功能的“隱形斗篷”一般要通過兩個關鍵的工作進程,其中之一就會扭曲入射光線,當對一個蘋果進行偽裝時,對稱性效應就會將在蘋果的兩側形成“幽靈”香蕉的圖像,其結果會使得一個蘋果看上去像一根香蕉。該技術不會完全將蘋果隱形,而是扭曲了它的圖像,使之看上去要小得多。
    
    
     Researchers say the technique is far simpler than current 'cloaking' devices
    Chinese researchers have revealed a 'ghost cape' that can make one object
    appear to look like another.The team from Southeast University in Nanjing,
    China say their technique is far simpler that other invisibility devices,
    because instead of making an object disappear entirely, it makes it look like
    something else.The technique scatters incoming light to create two 'ghost'
    images either side of the cloaked object.
     The new technique could be used by the military to make fighter planes such
    as this Lockheed Martin X-35B appear to be passenger airlines'The creation
    of wave-dynamic illusion functionality is of great interests to various
    scientific communities,' the researchers led by Tie Jun Cui at Southeast
    University in Nanjing, China, say.
     They say their research could have 'unprecedented applications in the
    advanced-material science, camouflage, cloaking, optical and/or microwave
    cognition, and defense security, etc.'
     The team has already built a prototype device to show off their theory.
     Depending on the construction of the cloaking device, the shape and other
    properties of the ghost images can be altered. 'By using the space
    transformation theory and engineering capability of metamaterials, we
    propose and realize a functional 'ghost' illusion device, which is capable of
    creating wavedynamic virtual ghost images off the original object’s position
    under the illumination of electromagnetic waves,' they say.
     The original object, in the top picture, is 'ghosted' using the new technique to
    create a much smaller version, shown in the bottom image'The scattering
    signature of the object is thus ghosted and perceived as multiple ghost
    targets with different geometries and compositions.'Current invisibility
    cloaks work using a two stage process.
     The first is an invisibility stage which distorts incoming light to remove the
    scattering effect of the cloaked object, for instance an apple, before a
    second stage distorts the scattered light to make it look as if it has been
    scattered off another object, a banana, for example.
     The result is that the apple ends up looking like a banana.
     The Chinese team have found a way to simplify this process, abandoning the
    first stage.Their device takes the light scattered from the apple and distorts
    it to look like something else such as a banana, according to Technology
    Review. The symmetry of the effect means light is scattered on both sides of
    the apple, producing two 'ghost' bananas, one on each side of the apple.
    
     The technique does not remove the apple entirely but distorts it, making it
    appear much smaller.So the result is that the apple is changed into a much
    more complex picture that is significantly different from the original.The
    team say this technique could one day be scaled up to create 'ghost' planes,
    for instance.The cloak itself is fashioned out of thousands of split-ring
    resonators, a structure commonly used in metamaterials that affects
    electromagnetic waves.

    親 幻影坦克。。!
    
    幻影坦克 / Mirage Tank:紅色警戒以及尤里的復仇中盟軍的一款偽裝坦克,是愛因斯坦在德國黑森林中研發(fā)的一種坦克。雖然它無法隱形,但它卻可以利用先進的光線偏折原理可以偽裝成樹木(巖石或草叢)來隱藏自己。此外即使是偽裝狀態(tài)也可以用高熱能射線攻擊敵人,給敵人出其不意的奇襲,適合于防守和伏擊。怕心靈控制。
