Abstract

A uniform-brightness, high-gain projection screen is especially suited for reflecting radiation from a projector to a viewer who is spaced from the projector along a projection axis. The screen is formed with a plurality of reflective faces that each form at least a portion of a ring that is transverse to the projector axis, have different spacings from the projector and are axially tilted to set the projector-face angle equal to the viewer-face angle. The faces are preferably defined by a plurality of tiles that are bonded to the interior of a projection dome such as a flight simulator dome.
