Outline of Final Research Achievements

A hologram, which can reconstruct 3D images naturally, is planar in general, and its viewing zone is fundamentally limited by its shape. In this study, we proposed a tactical method to realize equal to or wider than the viewing zone of a hemispherical hologram in spite of a planar hologram used by utilizing a geometrical property of a convex parabolic mirror. At first, a convex parabolic mirror was fabricated by machining. Then, an efficient calculation method of the wavefront considering the parabolic mirror reflection was developed. Next, our proposal and its effect were successfully verified by an optical experiment.
