A new Technology

Have you ever dreamed to be in more than one place at the same time?

Is it even possible to do so?

Well, thanks to the new technology this is absolutely possible.

This technology is called "Hologram".

What does it mean?

Hologramis a  photographic images that are three-dimensional and appear as if it was real

    

 

How a hologram works?

These are two pictures that explain the working process of hologram

* For recording hologram

* For reconstructing a hologram

Wouldn't be better if we can use it to attend courses in different areas in the world without the need to travel there?

In my point of view I think that it would be amazing to do it also you can attend conferences or meetings in anywhere and just feel like if you were really present there.

These are some pictures of holograms:
