(a) Comparison between true $L_d$ and that predicted from an SM measurement $\tilde{\mathrm{\Sigma }}$ for samples with various thickness values ranging from 0.5 to $4\mu \mathrm{m}$. (b) Comparison between true $D$ and that predicted from an SM measurement $\tilde{\mathrm{\Sigma }}$ for samples with $L$ from 0.5 to $4\mu \mathrm{m}$, $L_n=1\mu \mathrm{m}$ (solid lines), and $L_n=2\mu \mathrm{m}$ (dashed lines).
