Stereoscopic display apparatus use a holographic phase distribution formed from two-dimensional images

摘要

Three-dimensional information for each object structure is used to provide a 2-dimensional plane to obtain a 2-dimensional image. Two-dimensional images by the projection seen from a plurality of points, which were finely divided on a hologram forming surface are formed on the 2-dimensional setting plane. As for an electronic hologram, a phase distribution at the hologram forming surface is calculated from the 2-dimensional images of each figure structure. The calculated phase distribution is displayed on a liquid crystal display or the like. A reference light is irradiated onto the phase distribution and is converted into an optical wave front, thereby displaying a solid image. In case of forming a hologram recording medium, each of the 2-dimensional images of a plurality of structures is multiplexingly exposed and the exposed regions are finely divided on a dry plate.
