Abstract
A pseudo light pipe comprises an input end, an output end and a light transmission medium. The input end collects rays of light from a light source. The output end outputs and collimates the rays of the light collected at the input end. The output end has a convex curvature. The light transmission medium interconnects the input and output end, and transmits the rays of the light from the input end to the output end. The convex curvature of the output end is selected to output parallel rays of light. A projection system incorporating the pseudo light pipe and a dual paraboloid reflector (DPR) system.
