Schematic of the simulated OCT setup. Lenses L1 and L3 have a focal length of f1,3 = 25 mm while lenses L2 and L4 have a focal length of f2,4 = 36 mm. The radius of the aperture placed between the lenses is h = 3.5 mm. The light source has a central wavelength of λ0 = 1.3 μm and a FWHM of Δλ = 170 nm. A fiber coupler splits and recollects the light so that the detector records interference fringes containing the depth information. In spectral domain OCT, the mirror in the reference arm does not need to be moved and a spectrometer detects a wave-number-dependent intensity. The model used corresponds closely to the setup of the “Thorlabs Telesto II”59.
