is it possible to have a hologram like in star wars?

Answer 1

No.

A true hologram (not just a 3D illusion) is a proper recording of the wavefront of an image. It is not taken using a lens, and it can be viewed from any angle. This is why it is so convincing - as you move your head you see the image exactly as it would have been from the new viewpoint. It is also why it cannot be projected - it makes no sense at all physically.

The other problem is that a hologram records the wavefront using the principle of interference. Basically, the object is lit using a source of monchromatic coherent light and so is the film. The light from object then leaves an interference pattern on the film. When this is lit using the same light source again, it recreates exactly the light pattern that was originally falling on the film.

This is very hard to extend to full colour light, and very hard to use for real scenes.

Answer 2

If you are asking about projection of a 3-D image of a person, a holographic projection, I believe this was done some time back using laser. So far, a full colored model has not been tried yet. Guess it will be a matter of time that when you use a projection phone, you can have the image of the person you are talking to, appearing in 3-D in front of you.

Answer 3

There was an Arcade in my area in the 80's and 90's that was know for it's cutting edge games. One of the video games in there used projections of actors instead of computer simulated characters. I'm not sure if the method was technically holographic but it did produce the desired effect. It actually looked like a little person was inside of the screen...which wasn't actually a screen but a staging area, and there was depth to the image.

Answer 4

Not using the method they use in the movies, ie. a simple projector. You need mirrors, you need smoke, you need to view the image within a very small angle of display.
