Figure 5
Reconstruction from experimental data, shown for one particular value of the SAW phase φ. (a) Reconstructed phase ϕ and beam profile (intensity) along the sample surface. The algorithm was initialized with a random starting guess (blue). The (real) beam profile was kept constant during the reconstruction process. (b) Experimental diffraction pattern compared with the reconstruction. Good agreement in the shape, amplitude and position of the satellite peaks is achieved. (c) Logarithmic error metric log10(E).
