Abstract
The present invention is a projection system which includes a plurality of screen segments, each defining a surface in the shape of an ellipsoidal segment such that each surface has a first focal point and a second focal point. The screen segments are arranged such that an edge of the surface of one of the screen segments is essentially adjacent along its entire length to an edge of the surface of another screen segment. The projection system also includes a plurality of projectors, equal to the number of screen segments. Each of the projectors projects an image upon one of the screen segments from the second focal point of that screen segment. Preferably, the screen segments are arranged such that the first focal points of their surfaces essentially coincide with each other.
