Fig. 3

The Mueller matrix BRDF at 633 nm shown in projected directional cosine space (vertical and horizontal scales −1 to 1). Each column corresponds to an incident angle. The top row shows the measured data, while the second row shows the fit to the phenomenological model for an isotropic medium with a linear wavelength dependence. The 11 element is on a scale from (black) 0.25 sr−1 to (white) 0.45 sr−1, while the other elements are shown normalized on a scale from (blue) −0.1 to (red) 0.1. Some regions are saturated on this scale. See Supplementary Information for tabulated data.
