3D Display

Abstract

The aim of this project is to develop an holographic 3D display using photorefractive polymer device (For an overview of different 3D technologies, click here).

Photorefractive polymers are dynamic, and fully reversible holographic recording material (see this section). So they can be used to write, erase, and refresh holograms. By writing the holograms at video rate, we ultimately can make a display.

Holograms are recorded into the polymer using the principle of stereography. This means the diffraction pattern is recorded pixel by pixel, and the data can come from various image sources,  like medical instrument, observation satelite, CAD models… And even our own live capture system composed of 16 cameras.

With this system, we demonstrated a telepresence application by filming a person in one room and sending the hologram data over the internet to be printed in another location. There the audience can see that person in 3D.

The current performances we have demonstrated are: 12×12 inches size, full color based on RGB, 2 second recording time (for 4×4″), full parallax, 45° angle of view, no material degradation over 2 years.
