Rotating hexagon reconstructed by electroholography

The movie shows a rotating hexagon reconstructed by our electroholography 3D display system. The system consists of 3 LCD panels(3*1920*1080 pixel CGH), a green laser and some lenses.
In principle, an electroholographic 3D display can reconstruct a natural 3D images in space. However, it is difficult to reconstruct such a 3D images.
The problems of the small size and the narrow viewing zone for a reconstructed 3D object are essentially caused by the rough pixel pitch and the low resolution of an LCD panel. In order to enlarge the viewing angle and the size, an LCD panel for a CGH must have a large displaying area and a minute pixel pitch, because the viewing angle is proportional to the displaying area and the size is inversely proportional to the pixel pitch, respectively.
For instance, a method solving the problems can equivalently enlarge the resolution and miniaturize the pixel pitch by tiling some LCDs and using lenses.

It is possible to combine virtual images with holographic plates. Nice job! :D
