Abstract: In one implementation, an apparatus includes: a display to emit light in a first wavelength range; one or more light sources to emit light in a second wavelength range; a camera to detect the light in the second wavelength range; and an eyepiece to reflect and refract the light in the first wavelength range while passing, without substantial distortion, the light in the second wavelength range, wherein the eyepiece includes two lens halves separated by a retarder that changes light in the first wavelength range from a first polarization to a second polarization different from the first polarization.

Abstract: An electronic device display and a display cover layer may be coupled to a housing. The display may have an array of pixels that are configured to emit light. One or more light redirecting elements may be incorporated into the electronic device that redirect and thereby change the direction of light rays emitted from peripheral pixels in the display. The light redirecting elements may be used to enlarge the effective size of the display, to create images on sidewall surfaces of the display cover layer, and/or to create diffuse glowing areas around the periphery of the device. Light redirecting elements may be formed as integral portions of a display cover layer, as laminated optical films on a display cover layer, or as coating layers on a display cover layer. Afocal optical systems may be formed by placing first and second light redirecting elements on opposing first and second sides of a display cover layer.

Abstract: A head-mounted device may have catadioptric lenses that each include a partial mirror, a quarter wave plate, and a polarizer. An optical system in the head-mounted device may have an infrared light-emitting device and an infrared light-sensing device. The optical system may illuminate a user's eyes in eye boxes and may gather measurements from the illuminated eye boxes for eye tracking and other functions. The optical system may operate through the catadioptric lenses. To enhance optical system performance, the polarizers may be wire grid polarizers that are formed from conductive lines that exhibit enhanced infrared transmission and/or the quarter wave plates may be formed from cholesteric liquid crystal layers that serve as quarter wave plates at visible wavelengths and that do not serve as quarter wave plates at infrared wavelengths.

Abstract: An electronic device may include a display with a concave surface. A linear polarizer may be formed on the concave surface. A quarter wave plate may receive light from the linear polarizer. A catadioptric lens may have first and second lens elements. The first lens element may have first and second opposing surfaces. The second lens element may have opposing third and fourth surfaces. The first surface may be convex and may face the display. The fourth surface may be concave. The second surface may be concave. The third surface may be convex and may match the second surface. An additional quarter wave plate may be formed as a coating on the third surface. A partially reflective coating may be formed on the first surface. A reflective polarizer may be formed as a coating on the fourth surface. An additional polarizer may be formed on the reflective polarizer.

Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have a pixel array that produces light associated with images. The display system may also have a linear polarizer through which light from the pixel array passes and a quarter wave plate through which the light passes after passing through the quarter wave plate. The optical system may be a catadioptric optical system having one or more lens elements. The lens elements may include a plano-convex lens and a plano-concave lens. A partially reflective minor may be formed on a convex surface of the plano-convex lens. A reflective polarizer may be formed on the planar surface of the plano-convex lens or the concave surface of the plano-concave lens. An additional quarter wave plate may be located between the reflective polarizer and the partially reflective mirror.

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: A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the display on the head of the user. The head-mounted device may have a left lens that directs images from the left portion of the display to a left eye box and a right lens that directs images from the right portion of the display to a right eye box. Each lens may include a lens element that is coupled to the display. The lens element may be attached to the display with a layer of optically clear adhesive or the lens element may be formed from gel that directly contacts the display. The lens element attached to the display may have protrusions or recesses to accommodate input-output components. A single lens element may be attached to both the left and right portions of the display.
