Holograms get real: Startup creates objects out of light and thin air
After countless disappointing versions of the technology, a startup called Light Field Lab has started production on a technology it calls SolidLight, which is designed to produce real-life holograms. ...
Essentially, they're causing waves of light to interact at a specific point, and that interaction is visible to your eye. By doing this a lot, they can create the illusion of an entire object "made" of light.
And when I say a lot, I mean a lot. Their 28-inch diagonal panel has 2.5 billionpixels. For comparison, a 4K TV has 8.2 million. They're envisioning holographic video walls made up of these smaller panels, with upward of 245 billion pixels. ...
SolidLight's pixels need to create specific colors in a specific place in front of the display so the image appears to pop out of the screen. ...
Some of you might be familiar with Yamaha's Intellibeam audio technology, which uses an array of tweeters to make it seem like sound is coming from anywhere in the room but the soundbar. This is essentially the same thing, just on a microscopic scale since waves of light are orders of magnitude smaller than the air molecules that make up soundwaves. ...
And because the tech is scalable, you could have a much larger display and much larger holograms. Imagine wall-sized holographic displays and how they could be game-changers for entertainment. ...
