Within a few years , we ’ll be able-bodied to take percipient pic of objects through clouds , smoke , or fog . We ’ll do it using quantum entanglement photographic camera . How do you translate theoretical physics into photography ? suppose you are test to photograph a gravy holder behind a bank of fog . You ’ll apply two light - sensible devices : get one at a sluttish source that ’s crystalise your fog - shrouded sauceboat ( such as the sun , or a searchlight ) ; then aim the other where you think the sauceboat is likely to be . Then you use a estimator program to aggregate the radiation diagram of photons you ’ve received from the object and the igniter .
Once the two patterns have been compared , you get a form of contraband - and - snowy silhouette of the object you want to snap . Scientists call this a “ spook exposure . ” University of Maryland physicist Yanhua Shih has been working on this “ specter photography ” for a while , and has been babble out to the military about using it in UAVs for photographing bomb damage through smoke .
According to the Air Force Times :
Albert Einstein explored the canonical inquiry behind ghost tomography — quantum entanglement — which he called “ skittish action at a distance ” in 1935 . Shih discover ghost imaging in 1995 , but the hypothesis has yet to leave alone the laboratory .
Air Force satellites could utilize spectre envision by pointing a idle detector toward the Earth ’s surface and another toward the sunshine . The technique could allow the service to penetrate clouds or the locoweed that follows airstrikes . . . Defense producer Lockheed Martin has shown interestingness in quantum web , acquire a U.S. patent in May to arise quantum microwave radar that could defeat stealth aircraft and find camouflage improvised explosive equipment and mines , grant to the letters patent .
I ’m still unclear on how this works if you do n’t know the precise location of the object you want to photograph .
