Horizontal cuts of the diffraction intensity |Ψz(x, y)|2 in logarithmic scale, computed with the 2D FFT technique, for a fixed size K = 32 768 and for various samplings σ. The occulteris a sharp-edged disk of radius R = 300 mm. The curves are shifted by two decades with respect to each other. From bottom to top: σ = 295.3 μm, 246.1 μm, 196.9 μm, 147.7 μm, 98.4 μm, σopt = 49.2 μm, 39.4 μm, 24.6 μm, and 19.7 μm.
