Fig. 1 — Schematic diagram of the modelled OCT system and the model itself. S_ill and S_det represent the planar surfaces upon which the illumination is introduced and the scattered field is detected, respectively. Scattering in free space is simulated by using a perfectly matched layer (PML) which absorbs incident radiation with very low reflection.
