Samsung scientists have created an interactive slim-panel holographic display that increases the viewing angle for 3D videos by 30 times.
Note – stereoscopic 3D – used by existing 3D TVs and movies – is not the same as 3D holography. A hologram creates images by recording the interference pattern of light across, traditionally, a film. Viewing a hologram is somewhat like looking at a 3D world through a window. As you physically move yourself to the left or right, the scene appears as if it were a real scene on the other side of the window – this means you can look slightly to the left and right of the object too.
A stereoscopic 3D image, on the other hand, presents two images – one to your left eye and one to your right eye. You cannot move your head around and see anything other than what was recorded in the two images.
The news article is not entirely clear but my interpretation is that Samsung has developed a digital equivalent of a holographic film that presents images via the interference pattern waveform of a hologram.
This would be a significant advance because holograms do not required 3D glasses for viewing.
