Now, US researchers affirm this daydream is really shut to reality.
A University of Arizona group says it has devised a network that can make a holographic manifestation show up in other place and refurbish it in nearby real-time.
The group tells the biography Nature that the growth has outrageous potential.
"We predict many applications, for e.g. in manufacturing," mentioned Professor Nasser Peyghambarian from Arizona's College of Optical Sciences.
"Car manufacturers or transport manufacturers could look at holograms and pattern their systems in actual time. They could look at 3D models and make changes as they go.
"Imagine a really complex surgical procession - then with this network surgeons around the world could participate. They could see the entire procession in real-time and in 3D, and help out," he told BBC News.
Ever given the Princess Leia disposition was magically projected in 3D during the initial Star Wars film, people have wondered if such a technology might really be possible.
The network demonstrated this week is far from the ended product, but it gives a really burly suggestion of what might be practicable with serve refinements.
At its heart is a new cosmetic shade element that will record 3D holographic images time and time again, every two seconds.
In the set up described in Nature, 16 cameras available 2D images of objects and people from multi-part angles That data was then sent to other place using a P.C. connection.
At the remote site, a laser was used to "print" the visible data on to the new photosensitive polymer. The 3D picture calm of the 16 perspectives decays naturally, but the laser can write the next "frame" before it entirely disappears.
The group formerly gave an refurbish on its work in a 2008 Nature paper. Back then, its 10cm-by-10cm, one-colour shade could usually be
The new 45cm-by-45cm, multi-colour shade is re-written in a hundredth of the time.
No eyeglasses are indispensable to see the images, merely a few form of illumination.
And different "standard 3D" TV or drive-in theatre that create a elementary parallax outcome in that any eye is offering one somewhat different viewpoint on the same object, the range of the holographic images is built from the many views of countless cameras.
Theoretically, say the researchers, it should be probable to plan a full 360-degree hologram, one where an particular station on one side of the shade sees the front of a printed intent whilst someone station on the other side of the shade sees its rear.
So whilst it is not quite Princess Leia being projected in giveaway space, the network could feasible create a really spherical telepresence.
The group concedes its antecedent network has a lot of growth forward of it, but the researchers think the first blurb products could be available in a few years' time.
One key allege indispensable is the capability to re-print the polymer at least 30 times a second. This would give a ample more practical clarity of movement. The shade itself needs to be done ample bigger and extra cameras would have to be incorporated to supply more item and at significantly aloft resolutions.
And all this would have considerable estimate and bandwidth implications that would expected confine the system's use to high-end applications - of course in the early stages of commercialisation.
"Coming up with improvements to the polymer is going to take a few time, and moreover forthcoming up with improved lasers is going to take a few time. In about two to 3 years, you should be able to do the aspects," mentioned Professor Peyghambarian.
"And then transferring that in to a product is going to take other 3 to 4 years. But I do not think there is any production that would stop us from getting there."
