Abstract

Polarization-sensitive optical coherence tomography (PS-OCT) for retinal imaging has been developed with time-domain or spectral-domain OCT using broadband light sources at 800-nm band. Recent studies suggested that a 1 μm band could achieve higher penetration for imaging the posterior segment of the eye. In this presentation, we demonstrate fiber-based swept-source PS-OCT at 1 μm wavelength. Birefringence of the posterior eye segment is measured with a single depth scan by using the method of continuous polarization modulation. To our knowledge, this is the first time to show the phase retardation image of the posterior eye segment at 1 μm wavelength.
