Probe calibration setup. The probe’s distal end faces an external linear polariser followed by a front-surface mirror. All 9 combinations of illumination/detection channels were sampled by appropriate switching at the probe’s proximal end. Three polariser orientation angles of θ = 0°, 30° and 60° were used for calibration.
