Outline of Final Research Achievements

In this research, a holographic printing technique based on wavefront recording has been developed. A holographic printer can fabricate a reflection-type hologram at 25cm of hologram size with 480 billion pixels of computer-generated hologram data. A potential to fabricate holographic optical elements (HOEs) with digitally designed optical function was also focused. A concave-mirror array and off-axis concave-mirror functions were implemented on the fabricated hologram. These HOEs were used as the optical screens for a lightfield 3D display and a projection-type holographic 3D display. The later display system reconstructs the holographic 3D image over 1m away from the HOE screen for reconstruction of deep 3D space.
