(a) Photograph of the clinical system with (b) clinical spectral domain optical coherence tomography system schematic. Light from a superluminescent diode (SLD) centered at 1,310 nm is directed into the optical circulator (OC) that passes the light into the fiber coupler (FC) that splits the light into the reference arm (5%) and the sample arm (95%). The light is collimated through a set of fiber collimators (Col). The reflected light from each arm is coupled back together through a set of polarization paddles (PP) and interfered with each other through the 5/95 fiber coupler (FC) and spectrally dispersed onto a line scan camera that serves as the detector.
