Abstract
We present computational refocusing in polarization-sensitive optical coherence tomography (PS-OCT) to improve spatial resolution in the calculated polarimetric parameters and extending the depth-of-field in PS-OCT. To achieve this, we successfully integrated SHARP, a computational aberration correction method compatible with phase unstable systems, into a PS-OCT system with inter--A-line polarization modulation. Together with the spectral binning technique to mitigate chromatic polarization effects in system components, we show image quality enhancement in tissue polarimetry of swine eye anterior segment ex vivo, demonstrating the potential of computational refocusing in PS-OCT.
