Sketch of the polarimeter apparatuses for the calibration and measurement procedures. a The setup for calibrating the polarization state generator (PSG) and polarization state analyzer (PSA). The PSG includes the coherent laser, a polarizer (P1), a quarter-wave plate (Q1), and the reflective path of the non-polarizing beam splitter (BS) successively along the optical path. The PSA has components of the transmission path of the BS, a quarter-wave plate (Q2) and a polarizer (P2). In step 1, the polarization properties of the calibration samples are extracted, serving to calibrate matrices for the PSG and PSA in step 2. b In the apparatus for measuring a sample under test (SUT), the calibration samples and the mirror are replaced with an objective, the SUT and a hemispherical mirror to retro back the impinging beam
