3D holograms on smartphones and tablets in the purest 'Star Wars' style’

A system developed by HP allows us to obtain holograms of photos that will be visible with a sense of three-dimensionality from two hundred points of view or from videos to 30 fps in 64 positions around you.

Researchers of HP have managed to obtain 3D holograms directly on an LED screen, without the need for complex glass or mirror systems. This technology will allow smartphones and tablets to create real three-dimensional images that are visible from any angle around the image..

This development has been carried out in the HP laboratories in Palo Alto (California), based on some modifications to a conventional LCD screen that allows observing a holographic-looking image from 200 points of view.

For the creation of the hologram, The system requires two hundred different images that can be digitally reconstructed but, In a probable future, the applications most used by screens will be created from computer-generated images.

The possibility of viewing the hologram from different points around it, offering a sensation of 3D presence and depth, is due to the use of refraction of all light rays to provide a different image to each eye..

For this, The screen uses nanostructured notches called o “addressed pixels” that direct light in different directions. That is to say, They are not flat pixels, but panels that reproduce images in different dimensions.

A conventional LCD screen has a layer of plastic or glass that directs white light through the display's color filters., polarized, and sends them to the users. The new 3D screen has been manipulated so that both the color and other properties of light can be modified by passing through the nanostructure.

This way, the number of “addressed pixels” that the screen has will determine the number of points of view that the hologram shown by the 3D device will finally obtain.. In this sense, Light passing through the conventional pixels of an LCD screen is blocked or allowed making a moving image.

With this system, We can obtain holograms of photos from two hundred points of view or of videos at 30 fps in 64 positions around you.
