Abstract
Common-path probes provide considerable advantages for fiber-based OCT due to intrinsic length and phase matching. However, the polarization state of the reference light is usually arbitrary and variable due to stress-induced birefringence in single-mode fibers, which complicates implementing polarization-sensitive OCT. Here, we present depth-resolved retardation measurements with a single-mode fiber-based common-path probe by utilizing the constrained polarization evolution and the mirror state phenomenon for reconstruction of the round-trip measurements in the case of arbitrary reference states. Thus, a compact and flexible polarization-sensitive OCT implementation is demonstrated.
