Polarization-sensitive optical coherence tomography (PS-OCT) can measure the depth-resolved birefringence of tissue. However, determining the depth-resolved optic axis orientation is challenging due to the round-trip propagation of the probe beam in tissue layers. This paper analyzed the optic axes of a multi-layer retarder with Stokes representation and proposed a computationally effective reconstruction algorithm of optic axes. Filaments of the 3D printer were measured by Jones-matrix OCT. The angles between the filaments measured from the reconstructed relative optic axis have a maximum difference of 21° from the estimation.
