Geometrical holographic display

Is it possible to realize a holographic display with commercial available components and devices? Is it possible to manipulate light to reconstruct light field without using coherent light and complicated optical components? Is it possible to minimize the amount of date involved in building 3D scenes? Is it possible to design a holographic video display that doesn't require huge computational cost? Is it possible to realize a holographic video display with portable form like a flat-panel display commercialized nowadays? This research gives yes answers to all the above questions. A novel geometrical holographic display was proposed, which uses geometrical optical principle to reproduce realistic 3D images with all human visual cues and without visual side effects. In addition, a least necessary light field representation was introduced which can provide guidance for how to minimize the amount of data involved when designing a FP3D or building 3D scenes. Finally, a proof-of-concept prototype is set up which can provide true 3D scenes with depth range larger than 5m.

Field reconstruction of holograms for interactive free space true three dimensional display

Holographic display can show pictures in the way that looks like the same with the real world, and is thought as the ultimate display technology. But due to the complexity of the traditional holographic technique, it can hardly be applied to commercial display systems. In this paper, the field reconstruction of holograms (or real-time reconstruction of holograms) method, which is more practical and better than traditional holographic technique in image quality, is first proposed for realizing the display of true 3D image at free space. By combining the advantages of geometrical optics and the wave optics, a true 3D display is successfully designed. And by designing an interactive image generation chip, the designed 3D display allows user to interact with the 3D image in the style that's natural to them.
