On the top, orders −1, 0 and +1 diffracted by the DMD with two gratings displayed. On the left, the dephasing is Δϕ = π∕2, on the right Δϕ = π. The plots below correspond to the intensity profile of the first order, perpendicularly to the fringes, for the two corresponding dephasings. Here G = 131.5 μm.
