Abstract

We have developed a holographic three-dimensional (3D) display with a wider viewing zone than conventional planar holograms by using a non-planar optical element generating a diverging spherical wave with a wide spreadangle. The convex parabolic mirror and non-planar holographic optical elements were used as such non-planar optical elements. If the computer-generated holograms are designed properly considering the reflection on the non-planar optical elements, a 3D object can be reconstructed inside them as a virtual image. Viewers can observe 3D objects from the periphery of the 3D object, and optical experiments successfully demonstrated our proposed methods.
