Abstract

This study introduces novel solutions for reconstructing the structure of transparent biological media within the framework of polarization-sensitive optical coherence tomography. Reconstruction of the geometric phase, based on a modified Mach-Zehnder interferometer, enables mapping of the polarization architecture of the object, specifically the orientation of collagen fibers throughout the longitudinal scan. By accounting for scattering centers both in the epithelium and keratocytes in the cornea stroma, the depolarization of the object signal can be evaluated, which increases the signal-to-noise ratio toward the useful signal by four times. The impact of scattering on the object signal was assessed through mathematical modeling within the Monte Carlo approximation..
