a–c, The far-field spatial profiles of H18 for e.e. = (NR − NL)/(NR + NL) –4% (a), 0% (b) and 4% (c), where a positive e.e. corresponds to a larger concentration of R-fenchone in the sample. d, Angle-resolved, radially integrated far-field signal of the outer ring of the spatial profile (∣kW0∣ > 10) as a function of e.e. The black line on the right shows the phase of the Fourier component of the spatial profile oscillating at frequency ℓ = 6 as a function of e.e. The overlapping red line shows the result accounting for intensity fluctuations. The π jump at e.e. = 0% indicates the enantiosensitive rotation of the spatial profile. e, The phase of the Fourier component is shown by a black solid line. The red line with circles shows the phase obtained, including the intensity fluctuations for e.e. between –5% and 5%.
