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 light field display is composed of a light source assembly (LSA), a collimating lens, an incoupling section, a spatial light modulator (SLM), and gratings. The LSA includes point light sources that emit light at different time periods. The collimating lens collimates light from the point light sources. The incoupling section incouples the collimated light to a waveguide. The SLM spatially modulates the collimated light. The gratings outcouple spatially modulated light from the waveguide, and for any given point light source of the point light sources, the given point light source has a respective corresponding grating of the gratings that outcouples from the waveguide light that originated from the given point light source. The spatially modulated light output in each time period forms a respective virtual emitter in an eyebox, and over the different time periods the virtual emitters in aggregate form at least one virtual object.

摘要： There is provided a photonic integrated circuit configured for low-coherence interferometry and in-field sensing. The photonic integrated circuit can include an opto-coupler that has a substrate substantially transparent to a specified wavelength of light and a waveguide configured to route a light beam having a center wavelength at the specified wavelength. The opto-coupler further includes a mirror disposed at an angle, and the mirror is disposed on an angled surface of the substrate, the angled surface being proximate to an output end of the waveguide. The opto-coupler further includes a beam forming element configured to collect light reflected from the mirror, and the waveguide and the mirror are integrated within the substrate.

摘要： An optical element may include two or more zones to perform functions in a head-mounted display (HMD) device. An optical component may include a first optical zone characterized by a first sag profile to correct a refractive error of an eye of a user and a second optical zone characterized by a second sag profile to redirect a path of an illumination light beam. A transition zone located between the first optical zone and the second optical zone may provide a smooth transition between the first optical zone and the second optical zone.

摘要： A head mounted display includes a display layer, an array of light sources, a first optical combiner, and a second optical combiner. The array of light sources are configured to be selectively enabled to emit non-visible light to illuminate a fundus of an eye. The first optical combiner is configured to receive reflected non-visible light that is reflected by the eye, direct a first component of the reflected non-visible light to a first camera to generate an image of the eye, and pass a second component of the reflected non-visible light. The second optical combiner is configured to receive a fundus imaging light responsive to the second component of the reflected non-visible light, and to direct the fundus imaging light to a second camera to generate an image of the fundus.

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.
