Figure 2
Simulated diffraction of a 5 × 5 grating. The distance between the apertures is 1 µm, and an 800 × 800 pixel detector of 0.5 cm size is used. Intensities are on a linear scale, and the ray weight is normalized to N, thus allowing the comparison for simulations with varying N. The three cases N = 108, 109 and 1010 are considered for comparison in the inset and the 1D plot. The diffraction patterns show slight blur and non-zero background for the first case, whereas they become clear in the others. The profile comparison (bottom plot) shows in detail the fluctuations for the three cases.
