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 a removable lens element and a non-removable lens element. The optical system may include a quarter wave plate that is coated to the non-removable lens element without an intervening adhesive layer. The optical system may further include a reflective polarizer and a linear polarizer. The removable lens element may be selectively attached to the optical system. The removable lens element may be separated from a non-removable lens element by an air gap when the removable lens element is attached to the optical system. The removable lens element may have a convex curved surface that conforms to a concave curved surface of the non-removable lens element.

Abstract: An electronic device may include a display panel configured to produce light and a lens assembly that receives the light from the display panel. The lens assembly may be a catadioptric lens assembly with a partially reflective layer, lens element, quarter wave plate, and reflective polarizer. Some of the light emitted by the display panel may be reflected by the catadioptric lens assembly away from the catadioptric lens assembly. A supplemental mirror may be used to reflect this light back towards the catadioptric lens assembly. The supplemental mirror may increase the field-of-view of images viewable through the catadioptric lens assembly. The supplemental mirror may have a dithered upper surface or a phase-shift mask.

Abstract: A head-mounted device may have a head-mounted housing and optical components supported by the head-mounted housing. The optical components may include cameras, movable optical modules, and other components. Each optical module may include a display that displays an image and a lens that provides the image to a corresponding eye box. Optical self-mixing sensors may be included in the optical modules and other portions of the head-mounted device to measure changes in optical component position. In response to detecting a change in optical component position, actuators in the device may be adjusted to move the optical components or other action may be taken to compensate for the change.

Abstract: An electronic device 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 first, second, and third lens elements. The first lens element may have a convex surface and a concave surface. The convex surface may have less curvature than the concave surface. An anti-reflective coating may be formed on the convex surface. A partially reflective mirror may be interposed between the first and second lens elements and a reflective polarizer may be interposed between the second and third lens elements. Alternatively, a partially reflective mirror may be interposed between the second and third lens elements and a reflective polarizer may be interposed between the first and second lens elements.

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. The optical system may include a quarter wave plate that is coated to the first lens element without an intervening adhesive layer. The optical system may further include a reflective polarizer and a linear polarizer. The linear polarizer may be formed as a coating directly on the reflective polarizer (without an intervening adhesive). A single circular reflective polarizer may be used instead of a quarter wave plate and a reflective polarizer. The circular reflective polarizer may be coated to the first lens element without an intervening adhesive layer. The circular reflective polarizer may optionally provide optical power to the lens module. The circular reflective polarizer may include a cholesteric liquid crystal layer.
