Abstract: A scanning device includes a substrate, which is etched to define a recess in the substrate and to define the following structures contained in the recess: At least first and second mirrors are disposed along a common axis of rotation. Torsion hinges extend collinearly along the axis of rotation and connect the first and second mirrors to the substrate so that the first and second mirrors rotate on the torsion hinges about the axis of rotation. Rigid struts are disposed alongside the axis of rotation and connect the first mirror to the second mirror so that the struts rotate about the axis of rotation together with the first and second mirrors.

Abstract: An optical apparatus includes an optically transparent slab waveguide including first and second, mutually-parallel planar faces and an edge non-parallel to the planar faces. A radiation source directs a beam of optical radiation to enter the waveguide through the first planar face at an entrance location and entrance angle selected so that the beam subsequently exits the waveguide at an exit location in a surface selected from among the second planar face and the edge. A scanning mirror is positioned to receive the beam that has exited through the surface and to reflect the beam back through the surface into the waveguide while the scanning mirror rotates about an axis parallel to the surface over a range of angles selected so as to cause the beam, after reflection back into the waveguide through the surface, to propagate within the waveguide by total internal reflection (TIR).

Abstract: A scanning device includes a planar scanning mirror disposed within a frame and having a reflective upper surface. A pair of flexures have respective first ends connected to the frame and respective second ends connected to the mirror at opposing ends of a rotational axis of the mirror. A rotor including a permanent magnet is disposed on the lower surface of the mirror. A stator includes first and second cores disposed in proximity to the rotor on opposing first and second sides of the rotational axis and first and second coils of wire wound respectively on the cores. A drive circuit drives the first and second coils with respective electrical currents including a first component selected so as to control a transverse displacement of the mirror and a second component selected so as to control a rotation of the mirror about the rotational axis.

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: 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: A scanning device includes a scanner, which includes a base and a gimbal, mounted within the base so as to rotate relative to the base about a first axis of rotation. A transmit mirror and at least one receive mirror are mounted within the gimbal so as to rotate in mutual synchronization about respective second axes, which are parallel to one another and perpendicular to the first axis. A transmitter emits a beam including pulses of light toward the transmit mirror, which reflects the beam so that the scanner scans the beam over a scene. A receiver receives, by reflection from the at least one receive mirror, the light reflected from the scene and generates an output indicative of the time of flight of the pulses to and from points in the scene.

Abstract: A scanning device includes a substrate, which is etched to define an array of two or more parallel rotating members and a gimbal surrounding the rotating members. First hinges connect the gimbal to the substrate and defining a first axis of rotation, about which the gimbal rotates relative to the substrate. Second hinges connect the rotating members to the support and defining respective second, mutually-parallel axes of rotation of the rotating members relative to the support, which are not parallel to the first axis.

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.
