White-light holographic display based on planar optics.
A novel method for designing, recording, and reconstructing a planar-optics display holographic doublet, composed of two holograms on the same plate, is presented. The first hologram traps a light from a white-light source into the substrate by total internal reflection, whereas the second hologram couples out the trapped light from the plate to form the reconstructed three-dimensional image. The method is illustrated with a holographic doublet recorded at 488 nm and read out with a white-light source. A sharp image with high efficiency was reconstructed.
