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 TiO_2 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 TiO_2 suspensions with three different particle concentrations are in excellent agreement with the size distribution measured with x-ray sedimentation.
