摘要： 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.

摘要： 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.

摘要： 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.
