Not Accessible

Abstract

We demonstrate a new approach for determining particle size distribution in concentrated suspensions from spectral measurement of isotropic scattering coefficients using steady-state, continuous-wave photon migration techniques. Successful recovery of particle size distribution for TiO2 suspensions in the form of a lognormal function is achieved through a regularized inverse algorithm, in which a synthesized scheme of Marquardt and Tikhonov regularizations has been incorporated. Our results for dense TiO2 suspensions with three different particle concentrations are in excellent agreement with the size distribution measured with x-ray sedimentation.
