1. An assembly comprising:

  • (1) a laser for producing an optical beam that can be modulated so as to enable time-of-flight ranging;

    (2) a subrange scanner positioned so that it can deviate the path of the optical beam; and

    (3) an interferometer, configured so that when it receives at least a portion of the optical beam from the subrange scanner, it can subdivide it to produce transmit and local oscillator beams, and combine the local oscillator beam with at least a portion of an appropriately directed received beam, if present, to produce a combined beam.
