Paper Abstract

Three-dimensional (3D) displays have various shapes such as plate, pyramid, cylinder, sphere and etc. Every shape has its characters. One of them, the spherical shape is totally symmetric around the center. We design our system in order to display the image inside of the crystal ball. Even though the spherical crystal ball has perfect symmetry, there are some significant difficulties in designing optics since the crystal ball has severe spherical aberration. To display 3D contents, we generate many views by digital micromirror device in high speed and change the propagation direction of each view by 2-axis scanning mirrors and relay lenses. Theses plural images correspond to views of 3D object inside of the crystal ball.
