Frequency-modulated light scattering in colloidal suspensions

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

Frequency-modulated light field fluctuations due to moving particles in colloidal suspensions are examined using heterodyne interferometry. The power spectrum is the combined result of a time-of-flight-related frequency distribution due to light scattering and frequency shifts due to the Doppler effect. An approximation model is developed based on diffusion theory and verified experimentally. The potential for application towards comprehensive diagnosis of both particle dynamics and optical properties of the examined media is discussed. (C) 2013 American Institute of Physics.
