Abstract: Mapping apparatus includes a transmitter, which is configured to emit at least one beam including a sequence of pulses of light toward a plurality of points in a scene. A receiver is configured to receive the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from the points in the scene. A processor is coupled to process the output of the receiver so as to generate a 3D map of the scene, while controlling a power level of the pulses emitted by the transmitter responsively to a level of the output from the receiver in response to one or more previous pulses.

Abstract: A beam generating device includes a semiconductor substrate, having an optical passband. A first array of vertical-cavity surface-emitting lasers (VCSELs) is formed on a first face of the semiconductor substrate and are configured to emit respective laser beams through the substrate at a wavelength within the passband. A second array of microlenses is formed on a second face of the semiconductor substrate, with the microlenses in respective alignment with the VCSELs so as to transmit the laser beams generated by the VCSELs.

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.
