Figures & data
FIG. 1 SEM images of observed pollen. Divided into four groups: spherical with a smooth surface (hazel, birch, elm), barbed (ragweed, sunflower), rod shaped or football like (red chestnut, willow), and pollen with an unassignable shape (pine) related to the others.
FIG. 2 (a) Side view of the setup, and a microscope image of a rag weed pollen placed on the fiber. (b) Top view of the setup. (Figure provided in color online.)
FIG. 3 Sideward and backward scattering pattern of a rotated willow pollen. The rotation is around the y-axis in steps of 30° from a to e. (Figure provided in color online.)
FIG. 4 Relations between the sideward and backward scattering hemispheres for a willow pollen with different orientations relative to the laser. (Figure provided in color online.)
FIG. 5 Sideward and backward scattering pattern for different pollen.
FIG. 6 Sideward and backward scattering pattern for different pollen.
