摘要： Optical or light diffusers (or, simply, “diffusers”) designed and manufactured to include numerous facets randomly arranged in cells or sets on the diffuser outer (or front) surface 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. Methods of designing or defining the facets of the diffuser is also provided. 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 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.

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： A visual display assembly useful as an authentication or anti-counterfeiting element. The assembly includes a substrate and, on a surface of the substrate, an array of micro mirrors receiving ambient light. Each mirror includes a reflective surface to reflect the ambient light to display an image that appears to float in a plane, which is spaced a distance apart from the surface of the substrate. The image includes a plurality of pixels, and the array of micro mirrors includes for each of the pixels a set of the micro mirrors each having a reflective surface oriented to reflect the ambient light toward a point on the plane corresponding to one of the pixels. Each of the sets of the micro mirrors includes a plurality of the micro mirrors, and the reflected ambient light each set of micro mirrors intersects to illuminate or write a pixel of an image.

摘要： Products, such as branding labels and currency, fabricated to include an optical security element. The optical security assembly may include a carrier film or substrate. An image element, e.g., a printed ink layer, is provided on a first surface of the carrier film/substrate, and the optical security assembly further includes an array or plurality of micro lenses on a second surface of the carrier film/substrate opposite the image element. In order to make the registration and print requirements easier, a mask is provided between the printed ink layer to define color pixels, and the printed ink layer is provided in the form of color blocks in a checkboard pattern with each block aligned with a portion of the mask and a subset of the holes or openings that define the viewable color pixels.

摘要： A visual display assembly adapted for use as an anti-counterfeiting device on paper currency, product labels, and other objects. The assembly includes a film of transparent material including a first surface including an array of lenses and a second surface opposite the first surface. The assembly also includes a printed image proximate to the second surface. The printed image includes pixels of frames of one or more images interlaced relative to two orthogonal axes. The lenses of the array are nested in a plurality of parallel rows, and adjacent ones of the lenses in columns of the array are aligned to be in a single one of the rows with no offset of lenses in adjacent columns/rows. The lenses may be round-based lenses or are square-based lenses, and the lenses may be provided at 200 lenses per inch (LPI) or a higher LPI in both directions.
