Simulated spectrum intensity and experimental diffraction pattern. (a) Intensity profile for the modelling binary grating profile. (b) Experimentally registered diffraction pattern of the binary grating. (c) Intensity profile for the experimentally reconstructed grating profile. The full-scale intensity is shown in the inset of each graph.
