Abstract: Optical diffusers are disclosed with improved optical properties and improve aesthetic designs. A micro lens array may be overwritten with randomly placed lenses. A light shaping diffuser may be included. The light shaping diffuser may have a microstructure that includes features that aid in camouflaging the micro lenses from consumers, improving the aesthetic appearance while retaining other desirable optical properties.

Abstract: An anti-glare film for a light source is disclosed. The light source may be a light source with a Lambertian distribution, such as an LED light source. The anti-glare film may include a micro-frustum array to reduce the angular distribution of the light source and thus reduce glare. In some implementations, anti-glare film may further include a light shaping diffuser.

Abstract: An apparatus, system, and method is described for partially or completely eliminating Moiré interference artifacts generated in a heads up display having a diffuser with a micro lens array. Each lenslet of the micro lens array is faceted with micro facets positioned at least partially randomized. Aspects of the faceting may be selected to prevent Moiré interference artifacts but permit the diffuser to be used in a heads up display.

Abstract: A micro-optic cell design with a regularly spaced micro-lens array, having a series of randomly positioned lenslets that have been digitally overwritten, wherein the overwritten area is greater than 0 up to 100 percent fill, and wherein a light shaping diffuser pattern is placed on top of the lenslets of the micro-optic cell.

Abstract: A micro-optic cell design with randomly positioned lenslets is provided herein that uses statistical reconstruction of a micro-lens array. A method of making an optical element, which includes a micro-optic unit cell comprising one or more lenslets, is also disclosed.

Abstract: An array of microstructures or frustums on a substrate for reducing glare for electronic device displays or windows. The microstructures are designed to nearly perfectly align with the pixels on the display to avoid adverse viewing effects, such as Moiré effects. Substantially all light from the environment illuminating the front side of the film containing the microstructures from all angles is not reflected to the primary viewer (often viewing at an angle normal to the film). Light illuminating the microstructure from the environment will reflect off the microstructures at angles greater than a defined threshold outside the primary viewers field of view. Thus, glare to the primary viewer is minimized while glare to other views who view from other angles than the primary viewer is increased. This increased glare for other viewers adds privacy for the viewing by the primary viewer.

Abstract: This application discloses an optical element having a refractive lens array and a diffuser, both positioned on the same side of the optical element. A method of manufacturing such an optical element is also described herein.

Abstract: An illumination system converting light beams into wide-angle light transmissions including i) a cylindrical member having a cone-shaped depression in a distal end; and ii) a semi-circular member having an inner radial surface adjacent to a sidewall of the cylindrical member; and angled upper and lower annular surfaces extending from the cylindrical member and meeting at an outer radial edge. A light beam entering the proximal end of the cylindrical member strikes a first edge of the cone-shaped depression and is reflected out as a first light transmission; or it strikes a second edge of the cone-shaped depression, is reflected against the upper and lower annular surfaces, and exits the cylindrical member as a second light transmission parallel to the first diffused light transmission. At least one light path passes through a diffuser on the cylindrical member.

Abstract: The present disclosure provides an anticounterfeiting system based on optical technology that verify the authenticity of protected cinema screens. The optical technology includes taggants embedded or attached to the screen and an optical readout system that can interrogate the taggant layer and receive the taggant output. The taggants are capable of reflecting a pattern that unambiguously demonstrates that the screen contains the taggant. The taggants are covert because they are not visible under normal lighting conditions or during cinema operation, but are detected when interrogated by the optical readout system.

Abstract: The optical diffuser mastering of the subject invention includes legacy microstructure surface relief patterns, along with smaller ones, overlaid on the larger ones. The characteristic features produced by the present invention will be found useful to eliminate visible structures in/on optical diffusers, such as those used in movie projection screens (utilizing either coherent (i.e., laser-generated) and non-coherent (e.g., lamp-generated) light), head-up displays (HUDs), laser projection viewing, etc., as the present invention produces much sharper images than those afforded by traditional holographic optical diffusers.
