(a) Multimodal polarization sensitive digital holographic and Raman microscope experimental setup. In the inset, the incident directions and the polarization states of the object and reference waves are highlighted. Abbreviations: M, mirrors; L, lens; BS, beam splitter; PBS, polarized beam splitter; NF, notch filter; HNF, holographic notch filter; DM, dichroic mirror; QWP, quarter-wave plate; HWP, half-wave plate; C, collimator; YF, fiber Y-splitter. (b) Polarization hologram. The inset shows the intensity of the fringe pattern. (c) Calculated phase map for one of the two polarizations recorded and the 2D view.
