I feel it’s safe to say that just about everyone of us has seen at least one Star Wars movie. Everyone has seen at least one scene or heard at least one quote from the series. One of the most popular being “Help me Obi Wan. You’re my only hope”. Our little R2-D2 showed a projected holographic image and back during that time, it was one of the coolest things to see even fake technology do something like that. We’re getting closer and closer to having holographic imaging become something that we freely view. While it may not be here completely, there is a new projector in the works that is showing how close we are getting.
The projector itself doesn’t show off holograms, but it does offer the next best thing; a glasses free 3D experience.
Everyone knows that holograms are extremely cool to look at and overall technically impressive. That being said, with the current technology and knowledge that we have right now, it’s also pretty darn pricey to create right now. Until that time comes that we can create these images at a more cost effective price, our friendly neighborhood researchers at MIT have been cooking up the 3D projector.
Using 3D imaging without the use of the glasses, it quite the task it would seem. Our boys over at MIT may have come up with the proper way of doing it however. They’ve utilized two liquid crystal modulators which will create different images by angling the light in different areas. This altered angling of the light particles will be able to create different images depending on your respective point of view.
Normally, most types of 3D imaging causes the image to lose a bit of its coloration. With the technology being implemented in the new projector, it will be able to keep the coloration and brightness from being affected too much. By using a computer graphics card, they will be able to sustain a lot of the images original data. This will mean that the brightness and color won’t be affected nearly as much as in other 3D images. So now, not only do you have a 3D projector that doesn’t require glasses, but it also maintains its image quality without being too affected.
The researchers have also developed specific lenses specifically for this projector. The lens should widen the viewing angle, allowing for a better picture. Mind you that this particular projector isn’t completely perfect yet, nor are they really designing it to be.
As they say, “you have to crawl before you can walk”. That is exactly the case here. We want the technology to create holograms at a cheap and cost effective price. That is still quite a ways away. We know that we saw it first hand when rapper Tupac came back from the dead to perform holographically at the Coachella Music Festival. The technology is here, we are still working out the kinks, but we are in the baby stages so that is to be expected. The fact that MIT is actually designing something like this for retail purposes, or even just to show that it can be done, just proves how much closer we’re getting to having our own Star Wars-esque holograms in our own homes and offices.
