  • My Physics teacher knew a guy who was trying to make a TV that worked with laser holograms, it would be true 3D, and you could look around the program, say if there was someone behind a couch, then you could look behind the couch and see. The only problem he had was making the signal, as the wavelength is different and can't be sent in normal TV signals or something.

  • An infinitely short period of time? Lol. That's not only untrue, but theoretically impossible. Every period of time can be cut into two parts.

    Good story other than that.

  • last pic he had a United nations had on with flag and the all seen eye.... eh..

  • It's still mysterious, god damn it! Showing us laserbeams and bleaching solutions is all good, but how does it WORK? What's the theory? I am no wiser now than I was before.

  • How do companies mass produce this?

  • I like it... I'd scare my neighbours, make them think the neighbourhood is haunted...

  • Let's get the rating up!!!!

  • Lol something called bleach

  • Wow!! Get rid of that music. I'm here to learn, not to be entertained.

  • great video, why is there over 200 idiots that hit the dislike button... what is wrong with you people, how do u not like holograms...

    my guess is that 200 semi-retards probably thought this was fake...

  • Look up hologrpahic hard drives, they were supposed to be released last year, they will 1$ Hoplograpic storage cards will hold 120,000 gigs of data.

  • How the hell is this rated 2 stars?

  • Nice discovery 4 ever :D

  • thank you. have not seen that explained in visual details before.

  • nice and interesting video! :)

  • so how can we see this technology be used in the future? I know people can buy holograms for their homes but what other ways can this technology be used as a consumer product? The video hologram he was showing at the end makes me believe this could be used somehow for the future.

  • Technically, 12 nanoseconds wouldn't be an "infinitely short period of time". It's only a 12 nanoseconds short period of time! =P

  • OK, so I see that a hologram uses an interference pattern somehow, but how does that same interference pattern allow light to be reflected in such a way as to produce the original image? I know that with ordinary film, the surface reacts to the intensity of incoming light (getting darker the more light there is--and hence what you get is a negative), but how do you get a piece of film to reflect directionally asymmetric light? Is there something special about holographic film that allows this?

  • Holograms can be done

  • Excellent explanation...clear voice and instructions.

    Thank you...

  • Ah! I looked straight at the green laser. I'm blind! That is cool.

  • I think computers in the future will be hologram 3d technology like in the movie The Time Machine (2002) when the guy pops up in a glass frame giving guy peirce information online etc.

  • thats amazing!
