Abstract:
A method for programming an active mirror to transform a plurality of contiguous light beams between a distorted wavefront and a plane wavefront, said active mirror having a plurality of individual facets with each facet being independently moveable along a respective substantially parallel path, wherein said method comprises the steps of:positioning a plurality of individual facets of said active mirror to respectively reflect a wavefront comprising a plurality of contiguous light beams;establishing a base datum for said facets, said base datum corresponding to a plane wavefront;measuring an individual deviation in phase shift for each of said contiguous light beams in the wavefront relative to corresponding said light beams in a plane wavefront; andmoving each said facet of said plurality of facets from said base datum through a distance on its respective path to minimize substantially all of said individual phase shift deviations, to transform the plurality of contiguous light beams between a distorted wavefront and a plane wavefront.
