Abstract

Polarization sensitivity is a powerful extension of conventional OCT, providing additional contrast for birefringent structures. However, its widespread clinical adoption is complicated by increased system complexity and cost. Single-input polarization-sensitive OCT provides an alternative which bypasses some of the hardware requirements but is prone to artifacts. Here we present a method utilizing existing polarization mode dispersion within the catheter in combination with optimization algorithms to accurately estimate the sample retardance. This strategy has been shown to suppress artifacts and improve agreement with conventional two-state PS-OCT, facilitating the clinical adoption using optimization methods to overcome hardware limitations.
