PANEL OF THREE-DIMENSIONAL RASTER IMAGE WITH CLOSED WAVEGUIDE Russian patent published in 2019 - IPC G09F13/00 G02B6/00 

FIELD: calculating; counting.

SUBSTANCE: invention relates to three dimensional still image reproducing means. Panel of a three-dimensional raster image with a closed waveguide is made of a raster plate and a projection plate that are tightly fastened together. Raster plate and the projection plate are made of transparent material. On the large faces of the raster plate, a reflective material is fixed, which together with the transparent material of the raster plate forms an optical waveguide. Through a reflective material located between the raster plate and the projection plate, in a periodic manner an engraver, laser or other method the point objects are applied. Point objects can be artificially created defects, or damage to the material of the raster plate, or foreign particles contamination, or spots of paint that scatter or reflect a stream of white light from the raster plate to the projection plate. Set of point light filters is placed on the face of the projection plate opposite to point objects. Each individual point filter colours a beam of light from a point object in its own direction in a colour corresponding to the volume image element displayed by this particular beam.

EFFECT: technical result is to simplify the technology of manufacturing a panel of a three-dimensional raster image, reducing the number of image defects, improving image clarity, widening the viewing angle of the image up to 180 degrees, increasing brightness, reducing energy consumption.
