From: Phase space of partially coherent light with discontinuous surfaces
Phase gratings. The total spatial extent of the gratings in (c), (d) and (e) is from −0.5 mm to 0.5 mm along the x axis. We only show the grating profiles along the x axis from −0.05 mm to 0.05 mm for a clear visibility of the periods. The parameters for the incident light source are σ = 5 μm, δ = 0.8 μm and M = 40
