Orientation of polarization states before and after transmission. The elliptically polarized beam propagates along z-axis, while minor a and major axis b of the electric field are in xy-plane. After a beam at a non-absorbing wavelength (λ=633 nm) is transmitted through a sample with photo-induced supramolecular chirality, b rotates by an angle of Δψ. ε denotes the ellipticity
