Schematic of a SEA SD-OCT system. SLD: super-luminescent diode; BS: beam splitter; ND: neutral density filter; : mirror. The inset shows the B-scan signal of period for the galvanometer scanner. The switch is turned off at .
Diagram of the spectrometer design.
(a) A typical point spread function, measured at . (b) Sensitivity degradation vs imaging depth . The solid straight line is the least square fit of the measured data points.
(a) Standard SD-OCT and (b) SEA SD-OCT images of in vivo human skin. The lateral B scan covers . The scale bar represents .
