Fig. 3. Imaging in the deep MS regime.

(A) The reflection matrix R associated to three 5-μm-diameter ZnO beads deposited on a glass slide. (B) Time-gated confocal image of the three beads in the absence of the scattering layer. (C) The reflection matrix R measured in the presence of a scattering layer (L = 6.2l_s) placed before the three beads. (D) Time-gated confocal image in the presence of the scattering layer. (E) The SS matrix R_s built from R using Eq. 3. (F) The three first eigenstates of R_s, |U_i ∘ V_i|, are combined to yield the smart-OCT image of the three beads in the presence of the scattering layer. Scale bars, 10 μm.
