- 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 the object at a 45?뿦 angle. This paper presents the full imaging chain for the tabletop holographic display based on capture, processing, and reconstruction of a 360?뿦 observable hologram of the 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 a side view perspective and numerical tilt correction for 45?뿦 angular mismatch between the acquisition and reconstruction systems. The second method presents a modified lensless digital Fourier holography for holographic recording of the 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.
