Full-color zero-order suppressed diffraction optics diffusing screen/louver filter laminate

An optical apparatus, comprising:

• a first plano-convex lens for focusing light incident thereon;
• a holographic optical element positioned adjacent to said plano-convex lens to receive said focused light and comprising means for diffracting a beam of white light incident upon any particular point on said holographic optical element from a predetermined direction toward substantially overlapping red, green and blue exit pupils;
• a louver filter positioned with respect to said holographic element so that light passing through said element impinges on said filter, the diffracted light being transmitted through said filter and the undiffracted light being blocked by said filter, said filter comprising a thin flexible translucent substrate and a plurality of opaque louvers which are aligned parallel to each other when the substrate is planer;
• and
• a plano-concave lens and a second plano-convex lens, said louver filter being laminated between said respective lens, the curvature of the respective concave and convex surfaces of said lens being selected so that each of the louvers comprising said louver filter are aligned with a viewer's line of sight at the exit pupil.
