Polarization-sensitive optical coherence tomography can be used to measure the
birefringence of biological tissue such as the human retina. Previous measurements with a
time-domain polarization-sensitive optical coherence tomography system revealed that the
birefringence of the human retinal nerve fiber layer is not constant, but varies as a function of
location around the optic nerve head. Here we present a spectral-domain polarization-
sensitive optical coherence tomography system that uses a spectrometer configuration with …

We describe a polarization sensitive spectral domain optical coherence tomography
technique based on a single camera spectrometer that includes a multiplexed custom
grating, camera lenses, and a high-speed three-line CCD camera. Two orthogonally
polarized beams could be separately taken by two lines of the camera as a result of
vertically different incident angles. The system could provide the imaging capabilities of a full
camera speed and increased measurable depth. The proposed optical coherence …
