Le programme

Evolution has endowed the human with a three-dimensional vision. We use it every day for the simplest tasks: to find your way around a room, drive a car, shake a hand. Unfortunately, we do not use it in areas where it would be very important: learn, plan, interact remotely. The reason is the lack of a powerful visualization device in three dimensions.

Before talking about technology, one must understand the fundamentals of the human visual system. I will begin my presentation by presenting the different mechanisms and signals allowing vision in three dimensions. From there, we will discuss a brief history of the means that were invented to reproduce some of these signals. We will review techniques such as anaglyphs, active and passive polarization, and parallax barriers. In this description, we will also include systems that are supposedly 3D, but not necessarily so, such as the "Pepper's Ghost" effect, or the image overlay.

Continuing our tour, we will see the advantages but especially the limitations of the most modern systems including volumetric projection, auto-stereoscopic screens (and integral imaging), and virtual or augmented reality glasses. This will lead us to define an ultimate and perfect system for absolutely reproducing all spatial visual indicators. We will see at this point that the wavefront is an important factor and one of the ways to reproduce it is holography.

After a brief introduction to diffractive optics and the generation of static holographic images, we will discuss dynamic holographic devices, with the computation of the diffraction mask, and phase modulation devices: liquid crystals, micro mirrors, acoustic cells optics, and photorefractive materials. We will see what are the limitations of the current technology and will take a look at the state of the research through the various published works with, if possible, demonstration videos of the different systems.

I will brighten the presentation with examples from science fiction that will demonstrate the benefits but also the possible applications.

Man is born to see in three dimensions, it is time for research to provide a system that lives up to our natural potential.
