A second polarization selective reflector positioned in a second orientation non-parallel to the first orientation, and adjacent to the first polarization selective reflector so that the second polarization selective reflector: receives third light in a fourth direction; redirects a first portion, of the third light, having the first polarization to a fifth direction that is non-parallel to the fourth direction; and receives fourth light in a sixth direction and transmit a first portion, of the fourth light having the second polarization.

Abstract: 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.

Abstract: A multipass scanner usable e.g. in a near-eye display is disclosed. The multipass scanner scans a light beam angularly, forming an image in angular domain. The multipass scanner includes a light source, a tiltable reflector, and a multipass coupler that couples light emitted by the light source to the tiltable reflector, receives the reflected light and couples it back to the tiltable reflector to double the scanning angle. Then, the multipass coupler couples the light reflected at least twice from the tiltable reflector to an exit pupil of the scanner. A pupil-replicating waveguide disposed at the exit pupil of the scanner extends the image in angular domain. Multiple reflections of the light beam from the tiltable reflector enable one to increase the angular scanning range and associated field of view of the display without having to increase the angular scanning range of the tiltable reflector.

Abstract: An optical assembly for projecting light output by a display includes an optical waveguide, a reflective optical element, and a in-coupler coupled with the optical waveguide. The reflective optical element is positioned to receive first light and to reflect the first light as second light. The in-coupler is positioned to receive the first light and transmit the first light toward the reflective optical element. The in-coupler is further positioned to receive the second light and redirect a first portion of the second light so that the first portion of the second light undergoes total internal reflection inside the optical waveguide. The reflective optical element includes a negative meniscus lens having a concave lens surface and a convex lens surface coupled with a reflective surface. The reflective optical element is positioned to focus the first light such that the second light is more collimated than the first light.

Abstract: Eye-tracking systems of the present disclosure may include at least one light source configured to emit modulated radiation toward an intended location for a user's eye. The modulated radiation may be modulated in a manner that enables the light source to be identified by detection and analysis of the modulated radiation. At least one optical sensor including at least one sensing element may be configured to detect at least a portion of the modulated radiation. A processor may be configured to identify, based on the modulated radiation detected by the optical sensor, the light source that emitted the modulated radiation.
