Editor's Notes
- Imagine that Japan would have been selected for the organisation of the 2022 World Championships Football and not Qatar and hence budgets would have been allocated to technological developments instead of airconditioning.

- The big questions is of course whether this is or was a realistic ambition! Before checking its feasibility, let us take a look at the problem from an historical perspective.
- In 1908 Gabriel Lippmann published “’Epreuves réversible donnant la sensation du relief” in J. Phys., providing an early insight in integral photography. He was the recipient of the Nobel prize in Physics for his method of reproducing colours photographically based on the phenomenon of interference. By creating standing waves in the photographic emulsion the smaller sliver halide grains aligned in a laminae structures, whereas there distance was depending on the wavelength of the incident light. After development of the film, only the corresponding wavelength would be reflected and as such the right colour would be observed. Lippman was also the thesis supervisor of Marie Sklodowska Curie. --- Lippmann made use of this phenomenon by projecting an image onto a special photographic plate capable of recording detail smaller than the wavelengths of visible light. The light passed through the supporting glass sheet into a very thin and nearly transparent photographic emulsion containing submicroscopically small silver halide grains. A temporary mirror of liquid mercury in intimate contact reflected the light back through the emulsion, creating standing waves whose nodes had little effect while their antinodes created a latent image. After development, the result was a structure of laminae, distinct parallel layers composed of submicroscopic metallic silver grains, which was a permanent record of the standing waves. In each part of the image, the spacing of the laminae corresponded to the wavelengths of the light photographed.
- 1922: First 3D feature film “Power of Love” The Power of Love is an American silent film and the very first 3D feature film worldwide. Here: "Le Fantôme de l'Opéra: Version Stéréoscopique" Teaser Trailer A (red/cyan anaglyph version). Anaglyph 3D is the name given to the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into perception of a three-dimensional scene or composition.
- 1948: Dennis Gabor invents holography and he received in 1971 the Nobel Prize in Physics for this invention. Gabor exploited the concept of interference of waves, like what happens with water waves. However, with light one requires coherent light sources. By combining a coherent light beam that reflected from an object and the “original” reference beam, the phase differences between the beams are captured by interference pattern. To reconstruct the object the hologram has to be illuminated by the same reference beam. It took however some time before the first lasers where available. Nowadays we have CCDs and SLMs to respectively capture and reconstruct the interference patterns. Gabor is also well known for his foundational work in the domain of time-frequency analysis, and I sure every engineer in this room has been confronted with the impact of his work.
- Hence, notwithstanding all this great research, we cannot say today that we have yet a lot of satisfying 3D displays. Discuss the different technologies.

- Football is an easy example: ‘easy’ sport with simple rules and simple geometry. But what happens if the scenes are getting more complex? … This is exactly what iMinds wants to target.
