Abstract
A display system has a display surface having a three-dimensional convex shape. A projection system projects an object field onto a continuous image field located on the interior of the display surface the display surface is extensive in its coverage, for example subtending an angle of at least 240 degrees to provide greater hemispherical coverage.
Claims43
A display system comprising:
- a display surface having a three-dimensional convex shape;
- and
- a projection system for projecting an intermediate image at an object field, the intermediate image to be passed through a lens system, onto a continuous image field on an interior of the display surface, wherein the projection of the intermediate image on the continuous image field is substantially in focus on the interior of the display surface, and wherein a ratio of a longest image distance to a shortest image distance is at least 1.75, and an image distance at an apex image point is longer than an image distance at a full field image point.
