    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: An optical device includes a transmitter, which emits a beam of optical radiation, and a receiver, which includes a detector configured to output a signal in response to the optical radiation. An active area of the detector has a first dimension along a first axis and a second dimension, which is less than the first dimension, along a second axis perpendicular to the first axis. An anamorphic lens, which collects and focuses the optical radiation onto the active area of the detector, has a first focal length in a first plane containing the first axis and a second focal length, greater than the first focal length, in a second plane containing the second axis. A scanner scans the beam across a target scene in a scan direction that is aligned with the first axis, and directs the optical radiation that is reflected from the target scene toward the receiver.

    Abstract: A scanning device includes a base containing one or more rotational bearings disposed along a gimbal axis. A gimbal includes a shaft that fits into the rotational bearings so that the gimbal rotates about the gimbal axis relative to the base. A mirror assembly includes a semiconductor substrate, which has been etched and coated to define a support, which is fixed to the gimbal, at least one mirror, contained within the support, and a connecting member connecting the at least one mirror to the support and defining at least one mirror axis, about which the at least one mirror rotates relative to the support.

    Abstract: An optical device includes a laser light source configured to emit a collimated beam of light, and a scanning mirror, which is configured to reflect and scan the beam of light over a predefined angular range. The optical device further includes a volume holographic grating (VHG), which is positioned to receive and reflect the collimated beam emitted by the laser light source toward the scanning mirror by Bragg reflection at a predefined Bragg-angle, while transmitting the beam reflected from the scanning mirror over a part of the angular range that is outside a cone containing the Bragg-angle.

    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 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: Optical apparatus (64) includes a stator assembly (47), which includes a core (78, 90, 91) containing an air gap and one or more coils (80, 92, 94, 116, 120) including conductive wire wound on the core so as to cause the core to form a magnetic circuit through the air gap in response to an electrical current flowing in the conductive wire. A scanning mirror assembly (45, 83, 85, 130) includes a support structure (68), a base (72), which is mounted to rotate about a first axis relative to the support structure, and a mirror (46), which is mounted to rotate about a second axis relative to the base. At least one rotor (76, 132) includes one or more permanent magnets, which are fixed to the scanning mirror assembly and which are positioned in the air gap so as to move in response to the magnetic circuit. A driver (82) is coupled to generate the electrical current in the one or more coils.
