How does it work? | Holographic display



the First hologram was obtained by the Hungarian physicist Denison Gabor in 1947 in the course of the experiments to increase the resolution of electron microscopes. He coined the word “hologram”, wanting to emphasize the complete recording of the optical properties of the object. Dénes a little ahead of his time: his holograms had lower quality due to the use of gas discharge lamps. After the invention in 1960, ruby-red and helium-neon lasers, holography began to develop rapidly. In 1968 Soviet scientist Yuri N. Denisyuk developed a scheme of recording holograms on a transparent photographic plates and obtained high quality holograms. And 11 years later, Lloyd Cross created a multiplex hologram, consisting of several dozen camera angles, each of which can be seen only at one angle. How does the modern holographic display — this is in the news today!
