Simulation results of the estimated second layer properties versus different thickness of the first layer. Data estimated from three sets of first layer properties and the first set of second layer properties (Table 1) were plotted in black and those from the second set of second layer properties were plotted in gray. (a) The fitted second layer absorption coefficients and (b) the fitted second layer reduced scattering coefficients. The dashed lines are the true values.
