(a) Simulated (solid lines) and measured (circle, diamond and triangular markers) wavelength scans of the π/3π phase grating configurations. The simulations were performed using the actual grating parameters from Table 2 and considering the polychromaticity of the beam. The performance of the previous setup is shown for comparison (triangular markers in green). (b) Measured visibilities for different G0 configurations for λ ≈ 4 Å using G1,π compared with their respective simulations (solid lines).
