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.
