    Abstract: A head-mounted display may include a display system and an optical system that are supported by a housing. The optical system may be a catadioptric optical system having one or more lens elements. In one example, the optical system includes a single lens element and a retarder that is coated on a curved surface of the lens element. The retarder may be coated on an aspheric concave surface of the lens element. In another example the retarder may be coated on an aspheric convex surface of the lens element. One or more components of the optical system may be formed using a direct printing technique. This may allow for one or more adhesive layers and one or more hard coatings to be omitted from the optical system. A lens element may be directly printed on the display system to improve alignment between the optical system and the display system.

    Abstract: An electronic device may have a housing with a display. A protective display cover layer for the display may have an image transport layer such as an image transport layer formed from optical fibers. Extruded filaments of binder material may be fused together to form a layer of binder for the image transport layer. Each filament may contain multiple embedded optical fibers. As a result of the extrusion process, the optical fibers may be characterized by increasing lateral deformation at increasing distances from the center of the filament in which the optical fibers are embedded. Tension variations and variations in the orientation angle of the fibers in the image transport layer can be maintained below desired limits to ensure satisfactory optical performance for the image transport layer. The optical fibers and binder may be formed from polymers or other clear materials.
