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.

Abstract: A display system may display image frames. The system may include a scanning mirror and an array of staggered light emitting elements. The light emitting elements may emit image light and collimating optics may direct the light at the scanning mirror, which reflects the image light while rotating about an axis. Control circuitry may selectively activate the light emitting elements across tangential and sagittal axes of the image frame while controlling the scanning mirror to scan across the sagittal axis.

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: Apparatus for mapping includes an illumination assembly, which projects a line of radiation extending in a first direction across a scene. A detection assembly receives the radiation reflected from the scene within a sensing area that contains at least a part of the line of the radiation, and includes a linear array of detector elements and objective optics, which focus the reflected radiation from the sensing area onto the linear array. A scanning mirror scans the line of radiation and the sensing area together over the scene in a second direction, which is perpendicular to the first direction. Processing circuitry processes signals output by the detector elements in response to the received radiation in order to construct a three-dimensional (3D) map of an object in the scene.

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.
