Illustration of Q4GOM in experiments for quantification of the phase retardance of biological and polarization sensitive samples. (a) Experimental setup using 4G optics module connected to microscope with a polarization adapted interference objective: P1–input polarizer, IL1, IL2–illumination lenses, MMO–Mirau microscope objective, BS1–pellicle beam splitter, QWP1, QWP2, QWP3–quarter-wave plates, M–reference mirror, BS2–beam splitter cube, TL–tube lens, GPG–geometric-phase grating, L1–first Fourier lens, P2–analyzer, L2–second Fourier lens and CCD–charged coupled device. (b) Polarization adapted Mirau microscope objective (MMO) used for imaging of isotropic samples. (c) Polarization sensitive transformation of light by geometric-phase grating. (d) Polarization coded waves in restoration of the birefringent retardance of the dynamic phase introduced by liquid crystals. (e) Polarization coded waves in the quantitative mapping of the geometric phase modulated by multi-functional polarization directed elements.
