Abstract: A mirror assembly includes a frame having a central opening and a mirror plate, which is contained within the central opening of the frame and is shaped to define separate first and second mirrors connected by a bridge extending between the first and second mirrors. A pair of hinges are connected between the frame and the mirror plate at locations on the central axis on opposing sides of the frame so as to enable rotation of the mirror plate about the central axis relative to the frame.

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: 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 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: 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: Apparatus for mapping includes a radiation source, which is configured to emit at least one beam of radiation, and a detector and optics, which define a sensing area of the detector. A scanner is configured to receive and scan the at least one beam over a selected angular range within a region of interest while scanning the sensing area over the selected angular range in synchronization with the at least one beam from the radiation source. A processor is configured to process signals output by the detector in order to construct a three-dimensional (3D) map of an object in the region of interest.
