Figure 6.

Results using polarized illumination and the total reflectance signal mirror can be applied to the case of unpolarized illumination and detection. (a) Comparison of average path lengths and reflectance intensities from Monte Carlo simulations using polarized illumination and (co-polarized + cross-polarized) detection $\left({\langle L\rangle }_{\mathrm{\sum }}^{MC}\right)$ with simulations using unpolarized illumination and detection $\left({\langle L\rangle }_{\mathit{Unpol}}^{MC}\right)$. The line of unity is shown for comparative purposes. (b) Comparison of the reflectance intensity for polarized illumination and (co + cross) detection $\left(I_{\mathrm{\sum }}^{MC}\right)$ with the total reflectance intensity in the case of unpolarized illumination $\left(I_{\mathit{Unpol}}^{MC}\right)$.
