WHITE-LIGHT HOLOGRAPHIC DISPLAY BASED ON PLANAR OPTICS

A novel method for designing, recording, and reconstructing a planar-o ptics display holographic doublet, composed of two holograms on the sa me 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 fo rm the reconstructed three-dimensional image. The method is illustrate d with a holographic doublet recorded at 488 nm and read out with a wh ite-light source. A sharp image with high efficiency was reconstructed .
