Abstract
A projection system comprising a liquid crystal light valve having a wider acceptance angle for incident light in a first direction than in a second direction transverse to the first direction and an illumination system. The illumination system provides light to the liquid crystal light valve at a greater beam spread angle in the first direction than in the second direction. The system also includes projection optics for receiving light from the liquid crystal light valve and projecting such light toward a projection surface.
