Future Technology:Using the Naked Eyes for 3D Displays

Did you ever imagine that one day it would be possible to view and enjoy 3D images without wearing the cumbersome glasses? Well the day is no longer far away as it is here and happening already. The technology that has been developed is best suited for viewing images in small devices like mobile phones, phablets and tablets. Data visualization is no more going to be the same as the possibilities are exciting. The technology was originally researched and developed by a group of scientists at Massachusetts Institute of Technology (MIT) coming under the group known as Media Lab’s Camera Culture.

Today, the technology is being further developed and adapted for use, by the electronics giant Hewlett-Packard (HP). It is not just stationary objects that can be viewed in 3D sans the special glasses; even images that move can be viewed comfortably from various angles, up to a distance of about 3 feet. Though it sounds so easy, it is not as easy as it appears or seems to be. Using complex optical trickery to create sufficient depth for viewing images in 3D on mobile devices is rather tough as the thickness of the display has to be reduced drastically, making it ultra thin, yet have very high-resolution.

We have heard of the refractive power of lens that is used in cameras and other devices. However, in this case technology needed to apply an effect known as “diffractive optic technology” light waves are deflected by an obstacle, resulting in the creation of the required 3D images that are visible to the naked eye. It may sound much like holography, which works on a somewhat similar principle. However, holograms are stationary and cannot be applied for moving images.

The technology is not very new and was thought of and experimented by Toshiba way back in 2010. During their participation in CEDEC, Toshiba unveiled 3D display that could be viewed by the naked eye. The images could be viewed from as much as 9 different viewing angles, without having to rely on special glasses. The technology used was the production of many rays of light that were projected at various angles. This created an illusory effect, and the same picture appeared different to the eyes, and there was almost no strain on the eyes.

Another interesting development is the development of a nano-engineered protector for the screens of ordinary mobiles that turns the images into 3D displays. However, one can view the images through naked eyes only through this special plastic film. The developers claimed that the images would be as clear as the ones seen through special glasses, and would be totally free of any distortion. Though this technology promised to be a less expensive, it did not really take off very well. The filter used, is a mere piece of plastic film that consisted of over half million lenses that were imposed on the surface of the film using nanoimprinting technology. The new technology that allows one to view images in 3D without the aid of glasses is certainly a revolutionary development that will have a profound effect in the market.
