Figure 2

Imaging performance of the OCT subsystem. (a) Lateral edge spread function of the OCT scattering contrast mechanism characterized by imaging a USAF resolution target. OCT lateral resolution is measured to be ~ 3.9 µm, with the 0.4 NA objective lens. (b) Axial PSF of OCT subsystem measured in free space. OCT axial resolution is measured to be ~ 10.1 µm.
