Abstract
Display systems for achieving collimated projection effects. For example, in a theatrical or concert installation, display systems can be used to project images of scenery that appear to be vast and at a great distant behind the viewing window. The system may include a flat panel display, a corrective mirror, and a concave mirror positioned for viewing by an observer. The corrective mirror pre-warps an image generated by the flat panel display and reflects the undistorted image onto the concave mirror such that the observer perceives the image generated by the flat panel display as being at a large distance. The corrective mirror does not distort with changes in viewpoint. In another implementation, the system may include a short throw projector generating an image, a free-form projection screen, and a concave mirror positioned for viewing by many observers through a viewing window.
