A display apparatus has a display to emit image-bearing light to a prism assembly that defines an optical path between an incident surface of the prism assembly and an output surface that is orthogonal to within +/−30 degrees relative to the incident surface, wherein the prism assembly has a curved reflective surface opposite the incident surface. The prism assembly encases a beam splitter at an oblique angle to the defined optical path and to both the incident and the output surface of the prism assembly. A shim, in contact against the display surface and against the incident surface of the prism assembly, defines a sealed air gap for light between the display surface and the incident surface. A frame houses the display, the shim, and the incident surface of the prism assembly, wherein the frame further provides connection features for coupling the apparatus to a head-worn article.

An optical assembly includes at least one substrate that provides a first curved surface and a second surface. The optical assembly also includes a beam splitter on the first curved surface, a reflector on the second surface, and an optical retarder disposed between the beam splitter and the reflector. The optical assembly is configured to receive first light at the first curved surface and reflect the first light at the reflector and subsequently, at the beam splitter before outputting the first light from the reflector. The first light is transmitted through the optical assembly at a first optical power. The optical assembly is also configured to transmit second light at a second optical power that is less than the first optical power. The second light is transmitted through peripheral portions of the beam splitter and reflector without reflection at the reflector.

An optical unit includes a first light source, a second light source, a rotary reflector that rotates about an axis of rotation while reflecting first light emitted from the first light source, and a projection lens that projects the first light reflected by the rotary reflector into a light illuminating direction of the optical unit to form a first light distribution pattern. The second light source is disposed such that second light emitted from the second light source enters the projection lens without being reflected by the rotary reflector. The projection lens is configured to project the second light into the light illuminating direction of the optical unit to form a second light distribution pattern such that the second light distribution pattern overlaps an end portion of the first light distribution pattern in a right-left direction.

An optical lens (10), a camera module (100), and an electronic device (1000), where light that enters the optical lens (10) is axially folded by using a reflex optical element in the optical lens (10), so that the optical lens (10) can have a relatively long focal length to achieve a long-range photographing effect, and the optical lens (10) has a relatively short total track length. Therefore, when the optical lens (10) is used in the electronic device (1000), thinning of the electronic device (1000) is not affected. In addition, no prism is required to implement optical path folding in the optical lens (10).

An optical device includes a lens element, a first scanning element, and a controller. The lens element directs first light emitted from the first light-emitting element and second light emitted from the second light-emitting element, to a predetermined position. The first scanning element is arranged at the predetermined position, on which first light and second light exiting the lens element are incident at mutually different angles. The controller provides light emission control to start light emission at light emission timings shifted. The first light-emitting element and the second light-emitting element is arrayed such that an optical axis of first light and an optical axis of second light are contained in a same plane. The controller controlees the light emission timings of the first light-emitting element and the second light-emitting element in response to rotation actions of the first scanning element.
