Abstract
An illumination system for a video-imaging device has a light source and a collector of light from the light source. The collector is formed according to the principles of non-imaging optics and receives a portion of the light from the light source. The collector is configured to reduce the angular distribution of the collected light from the light source to match the requirements of a digital pixelation device.
