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: An optical device includes a light source, which is configured to emit a beam of light at a given wavelength, and at least one scanning mirror configured to scan the beam across a target scene. Light collection optics include a collection optic positioned to receive the light from the scene that is reflected from the at least one scanning mirror and to focus the collected light onto a focal plane, and a non-imaging optical element including a solid piece of a material that is transparent at the given wavelength, having a front surface positioned at the focal plane of the collection lens and a rear surface through which the guided light is emitted from the material in proximity to a sensor, so that the collected light is guided through the material and spread over the detection area of the sensor.

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 scanning device includes a base and a gimbal, mounted within the base so as to rotate relative to the base about a first axis. A first mirror, which has a first area, is mounted within the gimbal so as to rotate about a second axis, which is perpendicular to the first axis. A second mirror, which has a second area that is at least twice the first area, is also mounted within the gimbal so as to rotate about a third axis, which is parallel to the second axis, in synchronization with the first mirror.

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. A receive mirror is mounted within the gimbal so as to rotate about a second axis, perpendicular to the first axis. A detector is mounted on the gimbal so as to rotate with the gimbal about the first axis and receive light reflected from the receive mirror while the receive mirror rotates about the second axis. A collection lens is mounted on the gimbal so as to rotate with the gimbal about the first axis while collecting the light so as to focus the light onto the detector by reflection from the receive mirror while the receive mirror rotates about the second 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.
