Abstract:
1. An apparatus for displaying 3D images, the apparatus comprising: a screen with diffusion characteristics for direction selectively forwarding light; a screen illuminating system, the screen illuminating system comprising a control system to control the modules; and means for imparting an exit divergence to the exiting light beams being transmitted through or reflected from the screen, the measure of the exit divergence substantially corresponding to the angle between neighboring emitting directions associated with the optically neighboring modules, so as to provide a substantially continuous motion parallax in the 3D image perceived by an observer; wherein the modules of the screen illuminating system comprise imaging means for generating each of the incident light beams with a convergent section for focusing each incident light beam on a point of the screen, where a convergence of the incident light beams is not greater than the exit divergence of the light beams exiting the screen.
