Abstract

We fit different analytical models to the OCT signal obtained from scattering Intralipid solutions in order to extract the scattering coefficient. These models are based on both single scattering models and multiple scattering models of the OCT signal. Using the statistical outcome of the fitting procedure we establish the most suitable model for each of the scattering coefficients μ_s = 2.5-26 mm^-1. Our results indicate that for our specific class of OCT systems and samples/tissues, it is justified to use the single scattering model to extract the scattering coefficient from samples with scattering coefficients up to 17 mm^-1.
