ABSTRACT:
An apparatus and an associated method for displaying 3D images includes a screen and a screen illuminating system. The screen has diffusion characteristics for direction selectively forwarding light. The screen illuminating system includes modules for generating light beams incident on points of the screen. The apparatus is configured to impart an exit divergence to the exiting light beams being transmitted through or reflected from the screen. Each module provides one beam in one direction with a convergent section. The beams are focused on the screen where the convergence (δc) of an incident light beam is not greater than the exit divergence (δx) of an exiting light beam.
