    摘要: An optical product that includes a transparent lens sheet, which has a first side with a plurality of side-by-side sets of linearly arranged lenses. Each of the sets of lenses is at a slant angle in the range of 10 to 46 degrees from a vertical or a horizontal axis of the lens sheet. The product includes an image layer that includes pixels from a number of digital images. The pixels are arranged in a pattern of pixel locations providing non-orthogonal interlacing of the digital images relative to each of the sets of the linearly arranged lenses. The pattern of pixel locations aligns a number of the pixels from each of the digital images to be parallel to a line extending through a center of the linearly arranged lenses in each set. Each of the linearly arranged lenses may have a round base, a hexagonal base, or a square base.

    摘要: An optical security element to limit counterfeiting. The element includes a lens array with a first side and a second planar side opposite the first side. A plurality of lenses are formed on the first side of the lens array, and an ink layer is provided proximate the second planar side. The ink layer provides an interlaced image, which includes a matrix of frame or image elements under each of a plurality of lens sets or “virtual lenses,” each of which includes at least four lenses arranged in a grouping with an equal or unequal number of lenses on a side (e.g., a 2 by 2 array or a 2 by 3 array). The interlaced element are arranged in non-sequential order in two interlacing axes (e.g., via non-sequential interlacing in both directions) to be distributed throughout an area under the at least four lenses rather than under a single lens.

    摘要: Optical or light diffusers (or, simply, “diffusers”) designed and manufactured to include numerous facets arranged in cells or sets in which the planar faces or outward-facing surfaces have orientations and transmission angles (as may be defined by direction cosines of normal) to redirect received light to a region or portion of a predefined light distribution. A method of designing or defining the facets of the diffuser is also provides as are methods of manufacturing the diffusers and apparatus or products that include the new diffusers (such as microdisplays and lighting components). The diffusers are optically designed to produce a user-specified distribution of light. The diffusers can be engineered through the configuration of the facets on its front or outer surface (light transmission surface) to produce nearly any type of light distribution or shape, and the diffuser design facilitates their manufacture using extrusion processes as well as other fabrication techniques.
