The MIT Holographic monitor is a 3-D images that floats in space. This system creates a 3-D hologram that pops out of the screen, showing the picture from hundreds of angles to provide a convincing sense of depth. The first sets will probably display videogames or animation because they are easier to render in three dimensions than is live action, which requires dozens of cameras to capture the necessary visual data.

How it Works?

First, the display converts the video signal into electricity that it uses to stimulate a slice of lithium niobate crystale, which produces sound waves in response to the current. These waves then diffract lasers through the crystal, turning them into hundreds of slices of light. That light travels through two mirrors that project it at various angles onto a screen, where the slices stack up on either side of the display to create a 3-D hologram.

The production of the holographic monitor will be estimated only later in 2012. However, the price is still unknown.
