摘要： A light source structure includes a vertical cavity surface-emitting laser (VCSEL) device having a top surface and at least one side surface substantially perpendicular to and adjoining the top surface. The VCSEL device is configurable to output directed emission of light through the top surface. The light source structure also includes a light barrier surrounding at least a top portion of the VCSEL device and separated from the at least one side surface. The light barrier is configured to receive spontaneous emission out of the VCSEL device through the at least one side surface.

摘要： A near-eye optical element includes one or more infrared light sources and an optical structure. The one or more infrared light sources emit infrared beams. The optical structure includes an optically transparent material disposed over the emission aperture(s) of the infrared light source(s). The optical structure includes one or more facets that diverge the infrared beams.

摘要： An apparatus, system, and method for an eye tracking system for a head-mounted device include a light source, an image sensor, and a frame tracking system. The light source and image sensor may be configured to determine absolute and relative eye orientations. The frame tracking system may be configured to determine the displacement of a head-mounted device frame relative to the face of the user. The frame tracking system may provide displacement data for the displacement of the head-mounted device frame to the eye tracking system to enable the eye tracking system to compensate for frame slippage, frame jostling, or other frame displacement (relative to the face of the user). The frame tracking system may include one or more position sensors disposed on the head-mounted device frame and logic configured to determine displacement data using information from the one or more position sensors.

摘要： An optical assembly includes an optically transparent substrate and a first lens removably coupled with the optically transparent substrate by one or more adhesive layers. The one or more adhesive layers are positioned between the optically transparent substrate and the first lens. Also disclosed are an eye-tracker and a display device, each of which includes the optical assembly.

摘要： Fabricating a prescription optical element include providing a glass substrate layer and coupling an optical plastic layer to the glass substrate layer. A prescription surfaces is formed on an eyeward side of the optical plastic layer that is opposite an object side of the optical plastic layer. The object side is a planar surface that overlays the glass substrate layer and the glass substrate layer has a glass thickness to provide rigidity to the prescription optical element.

摘要： A method for calibrating eye tracking data for a head wearable optical device includes receiving eye tracking data from an imaging device oriented towards a combiner. The method includes determining a gaze direction of an eye of a user based on the eye tracking data. The method includes receiving calibration data from the imaging device that includes an indication of positions of one or more calibration indicators. The method includes determining the gaze direction based at least in part on the calibration data received from the imaging device (or factors adjusted by the calibration data).

摘要： A near-eye optical device includes a transparent layer, an in-field illuminator, and a diffractive optical element (DOE). The in-field illuminator is configured to emit near-infrared light centered around a first wavelength. The diffractive optical element is configured to be illuminated by the near-infrared light emitted by the in-field illuminator. The DOE generates a structured light projection that includes dots that expand as the structured light projection propagates farther from the DOE. The structured light projection is directed to illuminate an eyebox.
