title: High-gain holographic screens.
abstract: A high-gain screen can be made as a sandwich of a hologram and a retroreflective screen material. When a hologram is used in front of the screen instead of the screen material alone, the position of high-brightness viewing can be moved to any desired angle rather than being directed back along the projection beam.
