Fig. 8.

Recovered $g_1(\tau )$ at r = 1 cm using MVIM, from $\kappa (T)$ for (a) without prior information i.e., $x_0=0$ (b) with prior information i.e., $x_0=1$; (c) Sensitivity curve is plotted as a function of $T/{\tau }_c$ [42], where ${\tau }_c$ was chosen as time $\tau$, when $g_1(\tau )=1/e\approx 0.37$. From this curve it can be seen that maximum sensitivity is achieved, when $T\approx {\tau }_c$; Recovered $g_1(\tau )$ from $\kappa (T)$ by (d) using optimal exposure range i.e., $T\ge {\tau }_c$ (e) iterative scheme; (f) Residual between original and recovered $g_1(\tau )$ using iterative scheme. Here the superscript M in the legend indicates that it is MVIM recovered and O indicates that it is original $g_1(\tau )$
