Abstract: Techniques for three dimensional displays are described. An apparatus may comprise a first prism array having a first set of faceted prism elements arranged to optically couple with a second prism array having a second set of faceted prism elements, the first prism array and the second prism array to provide a null refractive component when the first set of faceted prism elements are in a first position relative to the second set of faceted prism elements, and a directional refractive component when the first set of faceted prism elements are in a second position relative to the second set of faceted prism elements. Other embodiments are described and claimed.

Abstract: Lens systems and an array of lenses for reproduction, capture and display of three dimensional images. The arrays generally fall into two categories. The first type of array uses air as the low-index material. This type of array may be used, for example, in illuminated displays electronic image detection, machine vision, and real-time 3D video capture. A second type of array uses a fluoropolymer as the low-index material, and conveys a great preponderance all incident light to the image plane.

Abstract: A lens system which has a first optical boundary with a radius of curvature R, a second optical boundary located substantially a distance R from the first boundary, and a third optical boundary nearer to the second optical boundary than R. Secondly, a lens system providing optical field limitation using total internal reflection. Also, an array of lenses for reproduction, capture and display of three dimensional images discussed.

Abstract: A relief master is formed by assembly of previously molded, machined, or otherwise fabricated relief structures. The relief structures may be quite small and include a relief geometry, i.e., a topology of interest, and a positioning feature. The relief structures are mounted on a rigid (e.g., metal) substrate that includes a plurality of positioning features complementary to the positioning features in the relief structures. The relief master is assembled through selective application and positioning of the small-scale relief structures, and can then be used as a pattern for diverse surface replication processes, including the fabrication of durable metal mold faces for casting, embossing, compression molding, and injection molding of complex patterned surfaces.

Abstract: Lens arrays facilitate intermodulation of spatial and angular resolutions. The arrays are configured to have observable spatial resolutions significantly different from (and generally higher than) the pitch of the lens array, and may be used, for example, be used to simulate three-dimensional scenes.
