Abstract
The paper presents a proof-of-concept polarization-sensitive swept source optical coherence tomography (OCT) system that performs measurements of the retardance as well as of the axis orientation of a linear birefringent sample. The system performs single input state polarization-sensitive OCT and employs an optical module based on optically passive elements such as two beam displacers and a Faraday rotator. Our implementation of the PS-OCT system does not need any calibration step to compensate for the polarimetric effect of the fibers, and its operation does not require a balanced polarization-diversity detector. The optical module allows measurement of the two polarization properties of the sample via two measurements which are performed simultaneously.

Instead of compensating for the dispersion in the reference arm and for the nonlinearity of the tuning, the complex master slave (CMS) processing method is chosen [20, 21] (Figs. 3 (c) and 3 (d))
