Abstract
An optical engine in which full-spectrum light is split into its three primary beam components of red, blue and green, which components are then modulated by reflective or transmissive light valve structure and ultimately recombined for projection of a full color image, which engine includes a source of unmodulated full-spectrum light, and immediately optically downstream therefrom, a two-dichroic-surface V-splitter/mirror structure from which emerge the mentioned three primary beam components.
