Holography, i.e. the technology who bring us holograms, was developed since the Forties of the Twentieth century by the Hungarian scientist Dennis Gabor based on the registration of a web of very fine interference fringes by use of laser lights to recreate three-dimensional representations (technically speaking effect of parallax of the image) of the subject photographed.
The development of the laser since the sixties of the last century made it possible to make huge advances in this technology, so much so that some years holographic avatars are used to animate the windows of some clothing stores, as Mondivirtuali.it already told you.
7D hologram to create movies
Originally fixed, the holographic images (“holograms”) now are also movies more and more realistic because recently a team of Japanese scientists led by Professor Yoichi Ochiai develop holograms safe to touch, that can be touched without causing burns through the use of laser-fast combination of cameras and mirrors arriving at a resolution up to 200,000 points, or “voxels” (volumetric pixels) per second.
The latest applications of 7D holograms are in 7D movies, i.e. three-dimensional films to which are added more special effects such as weather conditions and approach the objects (or “gliding walk”).
If you want an example of the degree of realism obtained by 7D holograms and movies, watch this video, made in 2014 in a shopping mall in Dubai.
Compared to viewers 3D virtual reality viewers do not have to adopt any device and therefore this technology is ideal for virtual themed parks or interactive movies.
7D movies even on tv?
A fascinating perspective, but some fear that such technology could be used (or has already been used) in a distorted manner, for example for military purposes or to achieve conspiracies, staging fake accidents that could lead to more or less wide conflicts.
