Abstract
The present invention provides a rear projection simulator system with a free-form fold mirror. The system includes a high definition projector and a curved screen. The free-form fold mirror is interposed between the projector and the screen. The free-form fold mirror includes one or more non-planar (e.g., curved) portions to eliminate or reduce loss of resolution of the projected image near the edges or boundaries of the image.
