Abstract
Wavefront refractor apparatus and method which records two Hartmann-Shack images simultaneously at different distances from the lenslet array. The two images recorded this way enable each focal spot to be associated with a lenslet forming the spot to identify “bad” spots, “ghost” spots, and to provide more accurate measurements for diverging or converging wavefronts.
