Figure 2: Simulated beam profiles after propagation through Overlayers 1–3 with increasing anisotropy from left to right compared to (left) propagation through a scattering-free (SF) overlayer.
From: Quantifying the influence of Bessel beams on image quality in optical coherence tomography
Degradation of a single beam profile versus propagation (DOF centre at 300 microns) for (a) Gaussian, and (b) Bessel beams on a linear amplitude scale, where 1 a.u. represents in each case the peak Gaussian field amplitude at focus after attenuation by the overlayer. Dashed horizontal lines in (a) and (b) show the locations of beam profiles presented in Fig. 3.
