  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.
