摘要: CEPM, Wroclaw University of Technology, Wroclaw, PolandReceived 02 September 2010, accepted 28 2010Published online 16 March 2011Key words Optical diagnostics, particle, aggregate, fractal, light scattering theories.This paper outline and discuss basic considerations for the optical characterization nanoparticles theiraggregates: particle models, theories main experimental setups, regarding their interest forthe study plasma flows. It emphasizes that there are now powerful alternatives to Lorenz-Mie theory andits simple homogeneous sphere model, which allow accurate calculations properties particleswith complex sub-structures shapes.
