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

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

Researchers from Hp have managed to obtain 3D holograms directly on an LED screen, no need for complex crystal or mirror systems. This technology will allow smartphones and tablets to create images in three dimensions that are real and visible from any angle around the image..

This development has been carried out in HP's laboratories in Palo Alto (California), from some modifications to a conventional LCD screen that allows to observe a holographic aspect image from 200 views.

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

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

To do this, the display uses nanostructured notches called or “addressed pixels” that direct light in different directions. I mean, are not flat pixels, but panels that reproduce images in different dimensions.

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

In this way, the number of “addressed pixels” with which the screen has will determine the number of points of view that will finally get the hologram shown by the 3D device. In this sense, light passing through the conventional pixels of an LCD screen is blocked or allowed to make a moving image.

With this system, we can get holograms of photos from two hundred points of view or videos to 30 fps en hata 64 positions around you.
