Accuracy of sample parameters measured from the FDTD-generated SM signal from a sample with a known thickness: (a) ${\tilde{\mathrm{\Sigma }}}_R/\sqrt{k_{c}L}$ and ${\tilde{\mathrm{\Sigma }}}_L$ as a function of the correlation length $l_c$ obtained for a sample with thickness $L=2\mu \mathrm{m}$ according to analytical equations (solid lines) and calculated from FDTD simulation (circles with error bars corresponding to the standard deviation between nine ensembles per statistical condition). (b) Corresponding true ${\sigma }_{n_{\mathrm{\Delta }}}$ and $l_c$ (solid lines) and reconstructed from FDTD-synthesized SM signal (circles with error bars corresponding to the standard deviation between nine ensembles per statistical condition).
