Star Wars style Holographic Display Technology is here!!






The resolution is too horridly low to be able to make out a face. That buzzing is a nasty side effect.
 
Not speaking about the power needed from the laser, heheh ..... ;)
 
^Very true.. the term was only used as a way of describing the technology. It's not actually a hologram.
 
I'm afraid I must take full responsibility for that.. In the actual paper, they don't call it a hologram. I just called it that in the title of the thread.. But my intention wasn't to mislead, I just thought there were some similarities.
 
Supposing we had a laser capable of 30khz and a good scanner set of 30kpps, and a framerate of 30hz, that leaves only 1000 points per frame. That is a grid of only 10x10x10, or if you just drew a surface in 3d, 30x30 pixels. There's little or no control over the brightness or color, so you're left with a black and white (NO GRAY) image the resolution of a typical windows icon. It's certainly cool, but it's not for faces.
 
In the words of Popular Science in 1949:

Where a calculator on the ENIAC is equipped with 18,000 vacuum tubes and weighs 30 tons, computers in the future may have only 1,000 vacuum tubes and weigh only 1.5 tons.

I don't want to give up on this technology quite yet, but it's not great in its current form.
