Natural (including biomedical) 3D disperse systems (DS) with nano- and/or microparticles
are inherently polycomponent polymodal polydisperse systems. Characterization of
such systems by different compatible non-destructive optical methods (refractometry,
absorbance, fluorescence, light scattering: integral and differential, static and dynamic,
unpolarized and polarized) is desirable because of feasibility to organize the on-line testing of
their state. At this road it is necessary to take into account peculiarities of inverse optical
problem solution for such complex systems (so called "three ill": "ill-defined" 3D DS, "illposed"
problems, "ill-conditioned" systems of equations). At the information-statistical
approach to the optical characterization and control of 3D DS it is possible to go round these
peculiarities and to qualify the 3D DS state changes.
