Quantum Ghost Imaging

8 May

Camera takes pictures of something it isn’t even pointed at, no mirrors involved thanks to Quantum Mechanics

This is really mind-blowing. The camera takes photos of objects it is not even looking at it. It’s creepy, kind of supernatural/psychic. There is disagreement among the scientific community ig ghost imaging is a quantum phenomena at all, but this latest experiment claims to demonstrate it is Quantum once and for all.

I love how all these experiments are done a few miles from my home

Here is the best article I could find explaining Quantum Ghost Imaging: http://spie.org/x8567.xml

Here is a diagram I created to help me try and understand how it works, and the diagram is showing how a spy satellite would work:

How Quantum Ghost Imaging Works

  1. Light is split BEFORE it hits the target by a special orbiting light splitting satellite, let’s say a military base is the target. It is hidden behind dense cloud cover.
  2. The ghost image taking spy satellite is equal distance from the splitter as the target is from the splitter.
  3. There is a photon detector on the splitter (d1). It will detect all sort of scattered photons and light being reflected back from earth, lots of noise and blurry stuff.
  4. There is also a photon detector on the camera taking satellite (d2). It too, will detect all sorts of noise from light reflected off everything.
  5. Anytime both d1 and d1 detect a hit at the exact same time, that is counted as a pixel towards creating the ghost image. This is why the satellite and target need to be the exact same distance from the splitter. Any photon hits that don’t occur at the exact same time are discarded as noise.

What is amazing about this, is that the resulting image will be clear and focused, as if the cloud cover is not there. Not only that the camera is not taking photos of light reflected off the target as occurs in classical photography and classical optics. It is only taking pictures of light that HAS NEVER INTERACTED with the target. That is mind-blowing.

The reason this seems to occur is when the light is split, the photons are entangled..whatever happens to one entangled photon happens to the other, no matter the distance. Einstein called this ‘spooky action at a distance’ and is completely unexplained.

This is just my amateur attempt at understanding Quantum Ghost Imaging, if anyone wishes to correct me please do so.

    This is incredible, but I of course now need to jump to the paranoid plane… Obviously this will become a tool to be used for spying on other countries, and eventually used by countries to spy on their own citizens… I just wish EVERYONE could focus on the wonders and beauty of science (like you and I do), rather than figure out ways to exploit it and use it to invade the privacy of others.
    Part of this may be due to me reading this book called “Little Brother”… has my mind going in a paranoid spin… hahaha.

      I have found rampant paranoia is a very common trait of most ex-JW’s (including myself)

        hahaha! Hey, we’ve got REALLY good reason for it! Being lied to and brainwashed and having your every action/thought controlled for 10, 20, however many years… yea, it’ll cause a little paranoia =P
        As I understand it, Congress will be voting this Summer on whether the right to bear arms applies to all citizens (as it does now) or only the government/militia. So, maybe well founded paranoia.

        It better apply to all citizens, disarming the citizens is the first step to establishing a dictatorship.

        Interesting times we live in. Though someone I work with said they try to take away the right to bear arms ALL the time… but this time is a little weird… its not getting any press coverage. I found out from a friend who is a member of the NRA. I haven’t even heard it on DEFCON, this group that jumps on ANYTHING that threatens the constitution… but maybe they are really run by the government.
        Yea, I can get on some pretty interesting tangents =P

        lol it’s quite alright I welcome it! If you ever use AIM or other messengers add me, I am bboyneko on AIM and bboyneko1 on yahoo

        Aw, I don’t have either of those 😦 I have msn… and I think that’s it.

    Infeasible. Cloud scattering adds random and unknown values to the flight time, and the alignment would have to be too precise. However, the technology may be useful in smaller, more controlled applications.
