Abstract:
1. An image generating apparatus, comprising: a plurality of image generating optical paths, each of said image generating optical paths having a respective intermediate face; a sweep mirror, common for said plurality of optical paths, that simultaneously deflects a received plurality of light beams of primary illumination light having coherence properties, each of said light beams being assigned to a respective one of said image generating optical paths, wherein each of said image generating optical paths includes, respectively, one of a plurality of image generating panels that generate respective partial images and display said respective partial images in one of the primary colors red, green, and blue, respectively, and means for illuminating said respective image generating panels, each of said means for illuminating having said respective intermediate face and modifying a respective beam of light to illuminate a respective image generating panel uniformly and with a beam shape being congruent to a shape of the respective image generating panel, wherein said sweep mirror is configured to simultaneously optically couple each of said received light beams into a respective assigned optical path to simultaneously irradiate each of said intermediate faces with a respective one assigned light beam, wherein said sweep mirror is configured to have, during said irradiating and by being tilted, each of said light beams, by reflecting said light beams into common or different directions, dependent on an angle of incidence of each of said light beams, subsequently in time irradiate different portions of said respective assigned intermediate face by sweeping each of said respective light beams across said respective intermediate face; a projection lens that projects said partial images received from said respective image generating panels and displayed on the respective image generating panels, wherein said projection lens has an aperture stop, and wherein each one of said intermediate faces of said respective means for illuminating is positioned in optical conjugation with respect to said aperture stop; three laser light sources that emit light of said respective primary colors and include optical means for converging respective light beams at common or different angles of incidence to a common point or region at said sweep mirror; and means combining said light beams of said primary colors emitted from said respective image generating panels into a common optical path.
