Abstract
A color display device is disclosed. The color display device includes an illumination lens system, a diffractive light modulation system, a combining system, a Fourier filter system, and a projection system. The illumination lens system converts a plurality of light beams into linear parallel light beams. The diffractive light modulation system produces a plurality of diffracted light beams having a plurality of diffraction orders by modulating each of the plurality of parallel light beams that are almost perpendicularly incident from the illumination lens system, The combining system focuses the plurality of diffracted light beams having the plurality of diffraction orders. The Fourier filter system selects diffracted light beams having desired diffraction orders using a dichroic filter. The projection system focuses the diffracted light beams on an object, and allowing the focused diffracted light beams to scan the object.
