Document Type and Number:
Japanese Patent JP2002162601
Kind Code:
A
Abstract:

To improve a stereoscopic visual device.

The reflected video display device of the specific visual point video display device reflects ray fluxes for illumination having directivity in accordance with the reflected video information from a video generator and irradiates a hologram plate with the reflected ray fluxes. The hologram plate diffracts the reflected ray fluxes to form a plane-form hologram image on or near the surface of the hologram plate and reflects the reflected video patterns on the reconstructed plane-form hologram image. The foci of the hologram plate are formed to a plane form in the position apart from the hologram plate by the diffracted ray fluxes. When the hologram plate is viewed within the range of the plane-form foci, the videos can be observed. The multivisual point image display device comprises the plural specific visual point video display devices.
