Abstract
A theatre system is described that includes a screen and a projection system. The projection system includes a first mirror and a second mirror that are positionable within axes for imaged light and between projection lenses of projectors and the screen. The axes include a first axis and a second axis. The first mirror and the second mirror are configured for causing the first axis and the second axis to be parallel to each other and to have a displacement between the first axis and second axis along a dimension by which the screen is curved.
