Comparing frameworks for analysis of diffusing wave spectroscopy experimental data
Diffusing wave spectroscopy (DWS) is a photon correlation spectroscopy method, which similar to dynamic light scattering (DLS), relates intensity fluctuations of scattered light to optical and dynamic properties of a sample. In this review, we focus on developing a quantitative comparison of the analysis frameworks that have been proposed for diffusing wave spectroscopy data, and the relative strengths and limitations of each approach. The theory behind DWS is presented and the relevant physical quantities that DWS can probe are discussed in more detail. We specifically compare Monte Carlo simulation and direct numerical simulation of the diffusion equation to obtain photon pathlength distributions P(s). We summarize the impact of associated with the selection of which simulation approach and its associated physical assumptions on the determination of the sample characteristics, including the mean squared displacement of the scattering centers dispersed in the sample and the mean free photon transport length.
