As indicated by your definition, the 3d-effect of a hologram arises from interference of a coherent light source. In the display that is shown in the video, the 3d-effect arises from light-emission (scattering) of a point source that moves around. The light from the point source need not be coherent for this display to work! Therefore, the term "hologram" seems inappropriate. I have never seen a hologram that is also a volumetric display. To me, this would be the holy grail of hologramming, since you could use interference for occlusion effects. |
