FIG. 11.
Schematic of the experimental setup of point-scanning super-resolution optical coherence tomography based on virtually structured detection. The focal lengths of lenses L1, L2, and L3 are 200, 40, and 150 mm, respectively. BS: beam splitter; CCD, charge-coupled device; CO, collimator; EOPM, electro-optic phase modulator; ND, neutral density filter; OB, objective (5× magnification, 0.1 NA); SLD, superluminescent laser diode.
