Figure 1
Diffraction of a radiation beam that strikes a diffraction grating with periodicity d with an angle of grazing incidence of ϕ, and which is diffracted by an angle of θ away from the surface. The situation is presented for a blazed grating with blaze angle γ. The illuminated area of width b is actively participating in the diffraction process. The radiation, being incident in the reversed orientation in the grey areas, cannot be diffracted by the common deflection angle.
