Abstract
The invention provides an image projection system including a first light source and a second light source. Light from the first light source is limited to a finite number of limited wavelength intervals. An imaging device is adapted for modulating light from the first and second light sources. A beam combiner is provided to combine light from the light sources and direct the combined light to the imaging device. Modulated light from the imaging device is directed to a lens.
