摘要： Methods and apparatus for fabricating light-emitting diodes (LEDs) that include polarizing or wavefront-altering optical components are described in which additional optical components are added to the LED package to filter or modify the polarization of the emitted photons. Packaged LEDs that include polarizing or wavefront-altering optical components are also described. The packaged LEDs may emit infrared light that is polarized or otherwise altered by the optical components added during the fabrication process.

摘要： A light detection and ranging (LIDAR) system has an emitter which produces a sequence of outgoing pulses of coherent collimated light that transmitted in a given direction, a mirror system having a scanning mirror that is positioned to deflect the outgoing pulse sequence towards a scene, and a detector collocated with the emitter and aimed to detect a sequence of incoming pulses being reflections of the outgoing pulses that are returning from said given direction and have been deflected by the scanning mirror. An electronic controller communicates with the emitter and the detector and controls the scanning mirror, so that the outgoing pulses scan the scene and the controller computes a radial distance or depth for each pair of outgoing and incoming pulses and uses the computed radial distance to provide a scanned 3D depth map of objects in the scene. Other embodiments are also described.

摘要： A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.
