DEVICE FOR HOLOGRAPHIC CONSTRUCTION OF THREE-DIMENSIONAL SCENES Russian patent published in 2010 - IPC G03H1/22 

FIELD: physics; image processing.

SUBSTANCE: invention relates to holographic reconstruction of three-dimensional scenes. The device includes an optical focusing device which directs sufficiently coherent light from a light source to the eyes of at least one observer through a spatial optical modulator which is encoded by holographic information. The device has several illumination units for illuminating the surface of the spatial optical modulator (SOM); each unit has a focusing element (21/22/23 or 24) and a light source (LS1/LS2/LS3 or LS4), which radiates sufficiently coherent light so that each of these illumination units illuminates one separate region (R1/R2/R3 or R4) of the surface; the focusing element and the light source move such that light radiated by light sources (LS₁-LS₄) converges near or on the eyes of the observer.

EFFECT: possibility of encoding a large area video hologram.
