ABSTRACT:
A projection system having an imager panel uses a scrolling prism assembly to illuminate different portions of the imager panel with light of different color simultaneously. The scrolling prism assembly can split light from a white light source into two or more different color bands that propagate through the scrolling prism in different directions, and it can reflectively combine the light so that the different color bands pass out of the scrolling prism assembly parallel. The scrolling prism assembly can also compensate for chromatic aberrations in the light received from the light source.
