Abstract

An optical projection system is disclosed. The optical projection system comprises a projection screen and a plurality of viewing stations. Each viewing station includes a beamsplitter, a projector including a lens, wherein the projector is directed at the beamsplitter, and a mechanical apparatus. The mechanical apparatus is adapted to optimize a quality of an image on the projection screen as seen by an observer looking at the beamsplitter. Projectors at different viewing stations are capable of projecting different images onto the projection screen.
