ABSTRACT:
RD 29133-17-A method for facilitating a reduction of speckle in a screen receiving light from a light source includes positioning at least one optical path distributing screen element such that the light originating from the light source passes through the screen element and emerges decorrelated from the screen element toward an audience space. The method further includes positioning an angular distribution element between the screen element and the audience space such that the angular distribution element distributes the decorrelated light from the screen element toward the audience space.
