a, Far-field spatial profiles for H18 and H19 obtained after Fourier transform with respect to the phase delay δ at the \(\tilde{\delta }=1\) Fourier component for H18 (top) and H19 (bottom). The left (centre) column shows the results for L(R)-fenchone, whereas the right column shows the difference signal SR − SL. b–e, Radially integrated signal as a function of the azimuthal angle of the far-field spatial profiles for H18 (b,c) and H19 (d,e). The solid red (blue) lines in b and d correspond to L(R)-fenchone, whereas the black lines in c and e show the chiral dichroism signal 2(SR − SL)/(SR + SL).
