Polarimetric analysis of a small piece of the Epipremnum aureum leaf (marked with a white rectangle in Fig. 1b). Different images of an inulin raphide, situated close to a stoma, are provided, which were obtained by using different channels: (a) Intensity; (b) PΔ; (c) P1; (d) P2–P1; (e) The sinus of linear retardance δ (stoma highlighted with a red arrow); and (f) Pseudocoloured image encoding retardance modulus and orientation. Pseudocoloured image comprises the linear retardance of the sample (shown into a white–black scale; radius of the semi-circular colour scale), and the fast axis orientation (represented with different colours; perimeter of the semi-circular colour scale).
