Patent ID: 8444272

Claim:
An apparatus for forming a color image comprising: at least a first, a second, and a third illumination source, each illumination source energizable to provide a continuous illumination of a first, a second, and a third wavelength band, respectively, to an optical multiplexer; wherein the optical multiplexer is actuable to cyclically switch the received light from each one of the at least first, second, and third illumination sources, in turn, to each one of at least a first, a second, and a third projector channel in a repeated sequence; wherein the first projector channel connects to a first projector apparatus, the second projector channel connects to a second projector apparatus, and the third projector channel connects to a third projector apparatus, and wherein each projector apparatus comprises a light modulator that is energizable to form an image from the light of the first, second, or third wavelength band that is cyclically switched onto its projector channel from the optical multiplexer.
