1. A laser distance and ranging (LADAR) array comprising:

  • a plurality of LADAR modules, each said LADAR module comprising a two-axis scan mirror configured to scan a laser beam through a field of view (FOV), and each said LADAR module configured to output a signal indicative of a distance between each said LADAR module and objects in the FOV that the laser beam is incident upon; and

    a central processing device communicatively coupled to said plurality of LADAR modules, said central processing device configured to generate an output based on combining the signals of each said LADAR module, wherein said plurality of LADAR modules comprises at least a first LADAR module having a first FOV and a second LADAR module having a second FOV, wherein said first and second LADAR modules are arranged such that the first FOV is non-overlapping with the second FOV, wherein the first FOV and the second FOV are adjacent such that an edge of the first FOV is aligned with and oriented parallel to an edge of the second FOV, wherein the output combines the first FOV and the second FOV into a third FOV, wherein said first LADAR module operates at a first phase and said second LADAR module operates at a second phase, and wherein the first phase is offset with respect to the second phase.
