Claim:
1. A system comprising a beam director and a multiplicity of laser channels arranged for transmitting light to and receiving light from said beam director, wherein each of said laser channels comprises: a laser for outputting a laser beamlet; a phase modulator for modulating a phase of the laser beamlet output by said laser; a polarizing beam splitter arranged such that a laser beamlet output by said laser will impinge on said polarizing beam splitter; a diverging lens arranged such that laser light transmitted through said polarizing beam splitter will impinge on said diverging lens, wherein said diverging lens is displaceable in three mutually orthogonal directions; a primary lenslet arranged such that laser light transmitted through said diverging lens will impinge on said primary lenslet and laser light transmitted through said primary lenslet will impinge on said beam director; a set of actuators for actuating displacement of said diverging lens in said three mutually orthogonal directions; and a focal plane array arranged such that light that passed through said diverging lens and then impinged on said polarizing beam splitter will impinge on said focal plane array, said focal plane array converting impinging light into electronic imaging data.
