Abstract: We report on Infrared Digital Holography (IRDH) and discuss the advantages offered by this technique. Efficient recording-reconstructions of IR holograms of various objects, which differ in composition and dimensions, are shown. We demonstrate optical holographic display by means of a liquid crystal based Spatial Light Modulator (SLM), which gives the chance to get direct 3D imaging and display of the IR holograms. Finally, 3D dynamical scenes can be numerically synthesized and displayed in the visible region, using holograms of different objects.
