Figure 7. Results for all five measurements. A, Hartmann-Shack (HS) images for all five aberrations showing HS spots with superimposed "centers of mass" (gray crosses) detected by our image processing algorithm. B, Two-dimensional view of the wave-fronts calculated from the Zernike coefficients retrieved from the HS spots in A and from Equations 6 to 13. C, Same as in B, but plotted as three-dimensional (x, y, z) graphs. D, Zernike coefficient values for each aberration. Notice that for the plane wave-front they are all zeros, as expected. These are the Zernike coefficients which are added to Equation 9 in order to retrieve the wave-fronts plotted in B and C.
