Claim:
1. An imaging assembly for directing a pattern of energy at a workpiece, the imaging assembly comprising: an illumination source that directs an illumination beam along an illumination beam path; a director assembly positioned along the illumination beam path, the director assembly including a plurality of director elements that are individually controlled to selectively adjust a shape of the illumination beam to provide a shaped illumination beam that is directed along a shaped beam path; a reticle that is positioned along the shaped beam path, the reticle including a plurality of spaced apart, transmitting regions that are organized in a reticle array; wherein the shaped illumination beam that is transmitted through the transmitting regions defines the pattern of energy that is directed at the workpiece; and wherein the reticle array corresponds to a plurality of post areas on the workpiece; and a control system including a processor that individually controls each of the plurality of director elements to selectively adjust the shape of the shaped illumination beam.
