Holograph is not in sci-fi now.

Have you ever seen this? In future, we can use this technique for making 3d Tivi, screen and need not bring a 3d glasses to watch 3d movie.

LCD, LED or even OLED will become outdated if we have a holograph device.

I still need 3d glasses. With a holograph image in front of me, it hurts my naked eyes to be honest.

Not really - a hologram need to project light to a reflective surface and holograms will never be able to match the properties of LCD's in their many forms..

Especially not if we want sci fi like air holograms - very little to reflect on there - water or smoker is better but still not good..

For a sharp image you need to reflect it onto something solid and when a surface can reflect light it doesn't become a very good screen

So as I see it it's a future supliment to modern screens, not a rival

Well, the Turkish Prime Minister already used holograms in a Star Wars-like mode: to deliver a speech.



Narendra Modi from India also made use of holographic appearences to give speeches, over a thousand of them at the same time.

Even if we have 3d holograms in a box, it's very interesting. In future, we can see my friend in a box when we are chatting. And if you want one aquarium in your room...

Now they can use 3d holograms to advertise their products.

You could imagine we will visit one future museum and animals, dinosaurs, objects... are showed in boxes. They looks like lively creatures in glass cages. Why don't you create one ghost now? It's amazing if they see one ghost that is made by 3d air holygram technique.

as you can see, in these pyramid holograms, the holograms are FLAT. They donīt change perspective as you move. There are only 4 flat faces... each side of the pyramid displays a face, but itīs not a true 3D object inside the pyramid.




as for these hologram public appearances, I still have not seen a single video showing it to be 3D. The camera is always on a fixed distant point and doesnīt move. How exactly is that an hologram? Seems more like a 2D projection of some kind.


an image like this is impossible:



you canīt project black light like the hair of the dude on the photo. In a movie theater or a household projector, what you see as BLACK is actually the WHITE CANVAS, which just happens to be not as illuminated as the rest of the image.

Thatīs why you need to see a projection preferably in a dark room. Otherwise the "blacks" become white, because the canvas is being illuminated by normal light. Your brain makes comparisons. You have two areas of the white canvas... one is not being illuminated if the projector was off, you would see it as gray. But when the projector is on, the areas next to it are BRIGHTLY lit by the projector (The more lumens a projector has, the more contrast) and therefore your brain compares the bright areas and now it "sees" the previously "gray" area as "black", because in COMPARISON to the very bright areas, itīs much darker.


the only real 3D holograms with good quality (that is, that are not projected precariously into water or smoke) we can achieve right now are still on flat panels.

There is one exception.

There was a japanese company who created the 'pixels' by focussing 2 lasers at a point in space. A single o2 atom would be heated up so fast that it was emitting light for a split second, thus creating a 'pixel'. By moving the lasers really fast (and using more than 2) you can create a simple image.

It was the closest thing I've seen to a real hologram from movies, since it was not a projection on some surface.

Edit: found it

I want to tell about holygraph, not holograph. It's association of hollywood and graphic. Very wonderful! However, it may be holograph now.

No, atmosphere. Otherwise it would be visible all over the planet, while in reality it only happens over the poles.
