Zusammenfassung:An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. The optical configuration may include a Fresnel lens assembly including a Fresnel lens and a reflective polarizer. The Fresnel lens may have a structured surface including a plurality of facets, and there may be a step between pairs of neighboring facets. The reflective polarizer may include a plurality of reflective polarizer portions, where each reflective polarizer portion conforms to a corresponding facet of the Fresnel lens. The reflective polarizer may be configured to reflect a first polarization and transmit a second polarization of incident light. The optical configuration may form an image of the display viewable by a user when the user wears the apparatus. Other devices, methods, systems, and computer-readable media are also disclosed.
