STEREOSCOPIC DISPLAY METHOD OF HOROGRAM AND ITS FORMING METHOD AND ITS STEREOSCOPIC DISPLAY APPARATUS

摘要

A hologram of a virtual object or an object which actually exists is formed and a solid image is displayed. 3-dimensional information of the object to be displayed is divided into zones in the depth direction. Depth images are formed as 2-dimensional images which are seen from a plurality of points which are obtained by finely dividing the hologram forming surface every zone. As an electronic hologram, a phase distribution at the hologram forming surface is calculated from the depth images and displayed on a liquid crystal display or the like. A reference light is irradiated to the display and is converted into an optical wave front, thereby displaying a solid image. In case of forming a hologram recording medium, a zone image corresponding to each of the finely divided exposure regions of a dry plate is multiple exposed.
