Optical Characterization of 3D Disperse Systems with Nano- and Micro- Particles: Polymodality of Size Distributions

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.
