Abstract
This invention is related to optical systems obtaining autostereoscopic type effects. Proposed method for spatial images and/or events observation, where stereo pairs images stream is projected and focused onto reflection hologram (9), which creates in space separate hologram surface viewing zones (11, 12) when the hologram is bearing at least one flat spatial holographic image part, which width is wider than human eyeball (20) width but narrower than an average human' interpupillary distance, said image part being observed as appearing in front of the hologram surface; and alongside it no other holographic image parts at a distance less than average.human' interpupillary distance are seen. A system for the invented method implementation is described.
