Abstract: Disclosed is an apparatus and method for digital holographic table top display. The digital holographic table top display apparatus includes: a camera array configured to capture a plurality of channel images in an omni-directional range from a table by using a plurality of cameras; a controller configured to detect an observer from the plurality of channel images and to track a position of pupils of the observer in at least one channel image from which the observer is detected; and a display configured to reproduce a digital holographic image in a three-dimensional (3D) space according to the tracked position of the pupils.

Abstract: Provided is a hologram generation method including receiving three-dimensional (3D) data information, determining a first projection position onto which the 3D data information is projected on a hologram plane corresponding to a first spatial light modulator (SLM), and a second projection position onto which the 3D data information is projected on a hologram plane corresponding to a second SLM, generating a first Fresnel zone plate (FZP) pattern corresponding to the first projection position, and determining the first FZP pattern to be an FZP pattern corresponding to the second projection position.

Abstract: An apparatus and a method for measuring quality of a holographic image are disclosed. The apparatus for measuring the quality of the holographic image may include an obtaining unit to obtain a hologram, a reconstruction unit to reconstruct a three-dimensional (3D) holographic image by irradiating the hologram with a light source, a measuring unit to measure depth of the reconstructed holographic image, and an analysis unit to analyze depth representation quality of the holographic image base on the measured depth of the holographic image.
