<p>A holographic full-color, data retrieval and projection system includes a holographic information storage plate that includes a plurality of reflective holograms, each designed to diffract light over a certain spectral bandwidth, and a holographic screen character plate, which includes a plurality of screen hologram character shapes that reflect diffracted light in a uniform, well-defined cone of diffuse light directed toward the viewer, producing images having high screen gain and high brightness, yet with lower power consumption than heretofore obtained.</p> |
