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： A waveguide for use in solar power systems to capture sunlight without solar tracking. The waveguide includes a first transparent layer with a first surface receiving sunlight, and the waveguide includes a second surface, opposite the first surface of the first layer, including recessed surfaces (or “microstructures”) each defined by sidewalls extending from the second surface toward the first surface of the first layer. The waveguide includes a second layer of transparent material with a first surface proximate to the second surface of the first layer for receiving a portion of the sunlight transmitted through the first layer. The second layer has a second surface, opposite the first surface, including recessed surfaces of the same or differing shape, size, location, and orientation as those of the first layer. The recessed surfaces of the first and second layers capture sunlight of differing ranges of incidence angles with total internal reflection (TIR).

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.

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 solar or photovoltaic (PV) system that includes a PV device with an upper surface configured for receiving sunlight and converting the received sunlight into electrical energy. An infrared (IR) reflecting film is placed over the upper surface to increase the efficiency of the PV device by retaining its operating temperature in more desired ranges. The IR reflecting film includes a substrate with a top surface and a bottom surface, and the bottom surface is mated with the upper surface of the PV device. The IR reflecting film also includes a plurality of structures, each with a recessed surface, formed on the top surface of the substrate. The IR reflecting film includes a reflective mask on the top surface of the substrate that includes reflective elements each disposed in the structures' recessed surfaces. In use, the IR reflecting film reflects sunlight having a wavelength greater than about 950 nanometers (nm).

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.
