Defocus subtracted SHWS lenslet image displacements calculated with search box sizes matching the lenslet central diffraction lobe and that provided by Eqs. (6) and (7) are shown for the human and mouse eyes with four different beacon illumination strategies and two different anterior to posterior reflectivity ratios. Each curve in the plots represents an illumination focus (from A-E, see Fig. 6). The shaded area (green) in these plots indicates the centroid repeatability (∼0.01 pixels) of our custom SHWSs using scientific-grade CCD cameras.
