Abstract: A device includes a substrate, an alignment structure disposed on the substrate, and a layer of a birefringent medium disposed on the alignment structure. The birefringent medium has an extraordinary refractive index, an ordinary refractive index different from the extraordinary refractive index, and an intermediate refractive index between the extraordinary refractive index and the ordinary refractive index. Molecules of the birefringent medium are configured to form helical structures having a helical axis. The layer is configured with an out-of-plane principal refractive index along the helical axis, and two equal in-plane principal refractive indices within a plane perpendicular to the helical axis. The out-of-plane principal refractive index is equal to the intermediate refractive index, and is substantially the same as the two equal in-plane principal refractive indices.

Abstract: Systems, articles, and methods that integrate photopolymer film with eyeglass lenses are described. One or more hologram(s) may be recorded into/onto the photopolymer film to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lens around the photopolymer film; sandwiching photopolymer film in between two portions of a lens; applying photopolymer film to a concave surface of a lens; and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.

Abstract: Disclosed are a device for protecting crops from wildlife, comprising an optical base film on both sides of which fluorescent holograms of natural enemies with both eyes and optionally claws or talons are laser printed while a composition containing a phosphorescent material and a repellent is applied to both eyes, and optionally to the claws or talons, and a method for fabricating the same. Oils and extracts from herbs are used selectively as ingredients in the repellent depending on repelling targets, that is, mammals, rodents and birds. In addition, the use of phosphorescent material exerts a repellent effect on nocturnal animals. Thus, the device exhibits high durability and can be used for protection from wildlife damage in various targets.
