Figure 4: Simulated total beam irradiance and image-carrying and -degrading components of the beam versus depth in the PSF phantom after each overlayer.
From: Quantifying the influence of Bessel beams on image quality in optical coherence tomography
(a) Axial ensemble-averaged profiles, for the (top) Gaussian and (bottom) Bessel beams on a logarithmic irradiance scale. (b) Radial averages of the ensemble-averaged transverse Gaussian and Bessel beam profiles on the same scale for the two depths indicated by the dashed lines in Fig. 2.
