Abstract
A system provides an optical image of an object. A first module (104) tracks a reference feature of the object. A second module (116) includes a source for an imaging beam, a scanning device to move the imaging beam along a portion of the object and a detection device receives a signal associated with an image of the portion of the object. The first module controls the position of the imaging beam relative to the reference feature to correct for the motion of the object. A third module (120) detects a distortion of the object and compensates for the distortion.
