Hello everybody, I am Chinese. Was pleased to find this site.
As an Avatar, 3D is very popular in our country
So I want to know, whether in foreign holographic display technology has matured
Have no business case?
I want to know the specific holographic imaging naked eye.
Geographical reasons of language, I can not always on to this forum, but I will come back to see everyone's message, I have MSN, looking holographic, 3D expert in this field and I can share, exchange.

holograms can be stored in a solid they cannot be projected into empty space.

most so called holographic projectors use a moving screen to create the illusion of projection - not very convincing to look at.
 
I disagree, Empty space doesn't exist, however as an avatar? I assume he means projected matter, is questionable. I have some concept of using existing matter, like an extremely high frequency of eddy current's to levitate aluminum and shape and move it. But this is only a flight of fancy and nothing more than a projection.
