Figure 1: Beam and sample configuration.
From: Quantifying the influence of Bessel beams on image quality in optical coherence tomography
(a) Schematic diagram of the beam, overlayer and imaging target, for transparent (top) and scattering overlayers (bottom). (Not to scale and not all pillars shown.) (b) The configurations implemented computationally (left), by simulating the one-way beam propagation through the overlayers, and experimentally (far right), by acquiring OCT images, here shown from an area bounded by a yellow dotted box in a macro-photograph (middle) of the target illuminated with a red beam.
