Theoretical analysis (Kramers–Kronig/Percus–Yevick) of the scattering properties of whole blood: a real part of the refractive index, b scattering coefficient, c scattering anisotropy (oxygenized and deoxygenized spectra overlap), d reduced scattering coefficient. For comparison, we also calculated the optical properties using the measured refractive index of aqueous haemoglobin (SO₂ > 98 %) from Friebel et al. [30] (grey lines), instead of the calculated refractive index through the Kramers–Kronig analysis
