Figure 6
A schematic of the PS-OCT setup. The abbreviations are in the following; WSL wavelength-swept laser, PC polarization controller, PMFC polarization-maintaining filter coupler, PMF polarization-maintaining fiber, PBSC polarization beamsplitter/combiner, GB glass block, VDL variable delay line, HSD high-speed digitizer. Black and colored fibers indicate single-mode fiber (SMF) and PMF, respectively. For the measurement of the melanin suspension, the eye was replaced with a mirror that directed the light downward, a relay lens and the sample on the glass slide.
