MIT researchers have created a cheaper alternative to 3D TVs: a 3D projector made from off the shelf parts. And the best part? It doesn't require any special glasses.
3D technology means that when viewing a film, you do it in multiple angles, which is why you have to use special 3D glasses. MIT's projector however, works with multiperspective. That means, you'll watch things on the screen like a hologram.
This new system uses two liquid crystal modulators, similar to LCDs in many TV's, that angle the way light comes into and out of the projector. The patterns created by the modulators for each frame of video gives each image a total of eight viewing angles.
The MIT team didn’t stop there, though. They also developed a new screen for their projector with wider viewing angles (an issue with current 3D display tech). Check it out below:
