(a) OCT B-scan of a 4-layer PDMS phantom; boxed portions mark positions of the magnified views shown in the table on the right. Reconstructions were created using (b) DRC, (c) DRC with 2D Gaussian smoothing, (d) DRC with TV denoising, and (e) DRC with iwhTV denoising. iwhTV denoising reduces noise while retaining the structure of scattering particles present in the sample (highlighted in columns A and B on the right). The white square in (a) represents 250 × 250 μm2.
