Fig. 1: Different scattering scenarios.
From: A boundary migration model for imaging within volumetric scattering media

Different columns show different scattering scenarios: imaging through scattering media with the increase of the scattering strength and the scattering region from (a–c) and imaging within the scattering media (d). The bottom row shows the synthetic temporal response under different scattering scenarios (synthetic data generation is described in Methods). According to Fermat’s Principle7, the red and green discontinuities in the transient measurements indicate that the vase surface shape is composed of a convex body and a saddle neck (details in Supplementary Note 7).
