Abstract: A method for depth mapping includes providing depth mapping resources, including a radiation source, which projects optical radiation into a volume of interest containing an object, and a sensor, which senses the optical radiation reflected from the object. The volume of interest has a depth that varies with angle relative to the radiation source and the sensor. A depth map of the object is generated using the resources while applying at least one of the resources non-uniformly over the volume of interest, responsively to the varying depth as a function of the angle.

Abstract: An optoelectronic device includes a display configured to emit first optical radiation in a first wavelength band through a front surface of the display. A planar optical waveguide, which is transparent in the first wavelength band, is overlaid on the display and is configured to guide second optical radiation in a second wavelength band along a direction transverse to the front surface. One or more diffractive structures are formed in the planar optical waveguide so as to couple the guided second optical radiation between the planar optical waveguide and a region in front of or behind the display.

Abstract: An augmented reality headset may include a reflective holographic combiner to direct light from a light engine into a user's eye while also transmitting light from the environment. The combiner and engine may be arranged to project light fields with different fields of view and resolution to match the visual acuity of the eye. The combiner may be recorded with a series of point to point holograms; one projection point interacts with multiple holograms to project light onto multiple eye box points. The engine may include a laser diode array, a distribution waveguide, scanning mirrors, and layered waveguides that perform pupil expansion and that emit wide beams of light through foveal projection points and narrower beams of light through peripheral projection points. The light engine may include focusing elements to focus the beams such that, once reflected by the holographic combiner, the light is substantially collimated.

Abstract: A direct retinal projector may include a gaze tracking system that tracks position of a subject's pupil and automatically adjusts projection of a scanned light field so that the light field enters the pupil. A control loop adjusts a scanning mirror to substantially center an IR beam on a position sensing detector (PSD). In so doing, the scanning mirror is correctly positioned so that the scanned light field from the projector enters the subject's pupil. In addition, a direct retinal projector may include an adjustable focusing element that adjusts focus of a combined light beam generated by a projector as the light beam is scanned to an ellipsoid mirror that reflects the light beam to the subject's pupil. The focusing of the scanned beam may be adjusted as the beam is scanned across the azimuth angle of the curved ellipsoid mirror.

Abstract: A direct retinal projector system that provides dynamic focusing for virtual reality (VR) and/or augmented reality (AR) is described. A direct retinal projector system scans images, pixel by pixel, directly onto the subject's retinas. This allows individual pixels to be optically affected dynamically as the images are scanned to the subject's retinas. Dynamic focusing components and techniques are described that may be used in a direct retinal projector system to dynamically and correctly focus each pixel in VR images as the images are being scanned to a subject's eyes. This allows objects, surfaces, etc. that are intended to appear at different distances in a scene to be projected to the subject's eyes at the correct depths.

Abstract: Optical apparatus includes a shaft, which is configured to rotate about an axis of the shaft relative to a base. A mirror is fixed to the shaft so that the mirror rotates about the axis. A rotor including a permanent magnet is fixed to rotate with the shaft. A stator is configured to generate a magnetic field having a DC component in a vicinity of the rotor. A torsion spring, extending along the axis, has a first end that is attached to rotate with the shaft and a second end attached to the base.

Abstract: A compact remote sensing device is described that includes a transmit component that scans a beam of light across a scene or object field, and a receive component that receives return light from the object field. The transmit component includes a small, fast scanning mechanism such as a MEMS mirror or a piezo mirror that scans a beam of light emitted by a light source across a field of view (FOV). The receive component includes a focal plane array (FPA) with a FOV at least large enough to capture the FOV of the scanning mechanism. The FPA may be a low resolution FPA (i.e., with fewer pixels than the resolution of the scanning mechanism), and the light beam may be scanned and captured at multiple spots within the pixels of the FPA.

Abstract: A Predictive, Foveated Virtual Reality System may capture views of the world around a user using multiple resolutions. The Predictive, Foveated Virtual Reality System may include one or more cameras configured to capture lower resolution image data for a peripheral field of view while capturing higher resolution image data for a narrow field of view corresponding to a user's line of sight. Additionally, the Predictive, Foveated Virtual Reality System may also include one or more sensors or other mechanisms, such as gaze tracking modules or accelerometers, to detect or track motion. A Predictive, Foveated Virtual Reality System may also predict, based on a user's head and eye motion, the user's future line of sight and may capture image data corresponding to a predicted line of sight. When the user subsequently looks in that direction the system may display the previously captured (and augmented) view.

Abstract: A method for depth mapping includes receiving optical radiation reflected from multiple points on an object and processing the received optical radiation to generate depth data including multiple candidate depth coordinates for each of a plurality of pixels and respective measures of confidence associated with the candidate depth coordinates. One of the candidate depth coordinates is selected at each of the plurality of the pixels responsively to the respective measures of confidence. A depth map of the object is output, including the selected one of the candidate depth coordinates at each of the plurality of the pixels.

Abstract: An optoelectronic device includes a substrate, having a recess formed therein. An optical isolator is mounted in the recess. A laser includes a stack of epitaxial layers on the substrate and emits a beam of radiation toward the recess along a direction parallel to a surface of the substrate. A waveguide directs the beam emitted by the laser into the optical isolator.
