摘要: Abstract The approximative computation of the distance distribution function p(r) is possible for light scattering data from nonspherical particles in ranges 1.0 ≤ m 1.3 and 2.0 α 12.0. This shown simulated prolate oblate ellipsoids. Mie effect depends on refractive index ratio largest three-dimensional volume element; i.e., case a ellipsoid, not controlled by length major semiaxis but size maximum cross section defined minor semiaxis. Any deviation spherical symmetry decreases effect. quality functions calculated allows classification structures suspended homogeneous, monodisperse particles. internal structure (radial polarization density profile) inhomogeneous can be computed with convolution square root technique, if are close to symmetry.
