Fourier digital holography of real scenes for 360° tabletop holographic displays

Recently, the tabletop holographic display has been introduced to present a large 3D hologram floating over the table. When the observer looks down at the hologram, the display reconstructs upper perspectives of object at 45° angle. This paper presents full imaging chain for the tabletop holographic display based on capture, processing and reconstruction of 360° observable hologram of real object. Two different imaging methods, which involve lensless Fourier digital holographic recordings and the tabletop holographic display are introduced. The first method utilizes the conventional capture approach with side view perspective and numerical tilt correction for 45° angular mismatch between acquisition and reconstruction systems. The second method presents a modified lensless digital Fourier holography for holographic recording of upper perspective. Experimental results including numerical and optical reconstructions present various visual aspects of both capture approaches such as viewpoint correction, refocusing, 3D effects, and 3D deformations.
