VIDEO HOLOGRAM AND DEVICE FOR RESTORATION OF VIDEO HOLOGRAMS Russian patent published in 2009 - IPC G03H1/00 

Abstract RU 2363025 C2

FIELD: physics.

SUBSTANCE: invention is related to holography. Device comprises optical system comprising at least one real or virtual point and/or linear quite coherent light source and lens, and also video hologram from cells regularly installed in the form of matrix or in any other manner. In observation plane that corresponds to plane of direct or reverse Fourier transform of video hologram, observation window is localised (5), which occupies a certain interval of restoration periodicity in the form of Fourier image of video hologram (3), through which it is possible to observe restored three-dimensional scene (6), at that length of observation window (5) does not exceed interval of periodicity in the plane of reverse Fourier image, and three-dimensional scene appears in the form of Fresnel image of video hologram.

EFFECT: possibility to receive topographical video images of long spatial objects of broad observation area.
