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.

Disclosed herein is a lens for a wearable projection system. The lens includes a holographic optical element embedded within the lens and covering a portion of the viewable area of the lens. The lens can be manufactured by filling a cavity in a lens blank with a photosensitive material and exposing the photosensitive material to a number of light beams to form the HOE.

The present invention relates to a security document and/or document of value with a hologram in a visually changeable window as a novel security element, and also to a method for producing the same.

A device for continuously replicating a hologram has a coating module to coat a liquid photopolymer onto a first carrier film, a lamination module to apply a second carrier film to the first carrier film coated with the photopolymer to obtain a photopolymer composite including a liquid photopolymer layer between two carrier films, an exposure module having a light source, and a master element with a master hologram to be replicated, and a fixing module to cure the replicated hologram in the photopolymer composite. The master element is axially rotatably mounted, and the exposure module is designed to bring the photopolymer composite in optical contact with the master element, while the light source exposes the master hologram to obtain a replicated hologram in a region of the photopolymer composite.

A method for continuously replicating a hologram by a device having a coating module, a lamination module, an exposure module and a fixing module involves coating a first carrier film with a liquid photopolymer using the coating module, applying a second carrier film to the coated first carrier film using the lamination module to obtain a photopolymer composite including a liquid photopolymer layer between two carrier films, bringing a region of the photopolymer composite in contact with an axially rotatable master element including a master hologram to be replicated in the exposure module, and exposing the region of the photopolymer composite to a light source, such that the master hologram is replicated on the photopolymer composite, and curing a replica hologram contained in the liquid photopolymer in the fixing module.
