Figure 6. Volume scattering function (normalized at e = 0° and for A = 550 nm) computed for various
organisms by using their refractive index and size distribution as experimentally determined (see text).
pattern (the number of which increases with increasing size) could only be observed for a
single perfectly spherical particle (or for a collection of spherical particles, if their size is
perfectly constant). They are quickly smoothed, as soon as sizes are not strictly uniform
within the population (and shapes not spherical). As examples, are shown the VSF computed
through Mie theory for several organisms when are used, as input parameters, the actual size
distribution functions determined with a size analyzer (100 channels) and the refractive indices
computed as previously explained (Ahn, unpublished).
