Simplified schematics of (PS-) µOCT imaging prototypes. (A) Bulk-optics Michelson interferometer with source, sample, reference, and detection arm. Additional components for PS imaging mode framed with dashed lines. (B) Polarization sensitive detection unit including two identical spectrometer units for PS imaging mode. SCLS – supercontinuum light source, LP – linear polarizer, BS – bulk-optic beam splitter, λ/4₁ – quarter wave plate at 45°, GS – 2D galvo scanner, OBJ – plan-apochromat objective, CO – cornea, ASC – anterior segment chamber, PR – pressure reservoir, λ/4₂ – quarter wave plate at 22.5°, M – mirror, G – diffraction grating, L – lens, LC – line camera, PBS – bulk-optic polarizing beam splitter, BB – beam block.
