Abstract
In this article is described a Real Time 3D video display of holographic images based on the principle of sequential scanning of holograms with HPO (horizontal parallax only) generated by a high speed computer and sent at high frame rate to DMD, and visualized by an anamorphic optical group. The device displays binary amplitude and phase modulated images opportunely synchronized and scanned by a galvanometric mirror or polygonal mirror driven by the control electronic circuitry. The elementary holograms are generated by a resident hardware which, through interpolation, generates single elementary holograms starting from images and depth map. The device operates with incoherent light (integral images) or with coherent light (holographic display) by changing the optical visualization group.
