Presentation Description :
Polarization-sensitive optical coherence tomography (PS-OCT) measures the depth-resolved polarization properties of tissue structures such as the retina. PS-OCT systems are often built with single-mode fibers to facilitate optical alignment, but can suffer in this case from wavelength-dependent polarization distortions, i.e. polarization mode dispersion (PMD), that distort the measurement of tissue polarization parameters. A novel Jones matrix analysis method is presented that corrects polarization distortions caused by the system hardware (including PMD) via wavelength-dependent analysis of the polarization states of the sample surface and deeper located birefringent tissue structures. This method was implemented for PS-OCT imaging of the retina and used for the en face visualization of the intensity, phase retardation and relative optic axis orientation in a healthy volunteer and a glaucoma patient.
