Holography is a three-dimensional (3D) imaging technique to reconstruct wave field of the light scattered by real objects. In this paper, we present two representative digital holographic data representations, 3D data-based representation and hologram-based representation, and compare compression efficiency of them.
An optical reconstruction of a complex hologram by use of an amplitude-only spatial light modulator (SLM) and phase-only SLM is presented. The complex hologram of diffusively reflective object recorded by optical scanning holography (OSH) is converted to an off-axis hologram to eliminate twin image and background noise. With respect to holographic luminance contrast ratio, the optical reconstructed...
This paper describes experimental demonstration of holographic 3D reconstructions with a directly-viewing, transmissive, amplitude-modulating 5.5″ LCD SLM device in monochrome. A full-complex field modulation is achieved by the single amplitude-modulation SLM module using the Burckhardt-encoding scheme at the cost of the decrease in sampling. We define an effective holographic contrast ratio for the...
