1. An apparatus, comprising:

  • a scan module having one or more laser sources that generate one or more initial laser beams and two or more beam deflectors that deflect the one or more initial laser beams;

    a beam optic configured to substantially collimate the one or more initial laser beams to produce one or more collimated laser beams;

    one or more beam deflector controllers configured to control the angle of beam deflection from each beam deflector;

    relay optics between the two or more beam deflectors configured to image each sequential beam deflector in an optical chain onto the subsequent beam deflector in such a manner that the beam deflecting from the last beam deflector in the optical chain contains a combination or superposition of all the beam deflections of the beam deflectors in the sequence, and maintains a beam divergence of the one or more collimated beams.
