Abstract

Polarization-sensitive (PS) optical coherence tomography (OCT) allows for depth-resolved measurement of light polarizing properties of different layers in the human retina. Since their inherent polarizing properties are different, the retinal structures can be identified using PS-OCT. We present an improved PS-OCT instrument for in vivo imaging of healthy and diseased human retinas. The system is based on spectral-domain (SD) PS-OCT operating at an A-line rate of 20 kHz. Different scan patterns and trigger signals are controlled by a field-programmable gate array (FPGA). By integration of an additional detection channel in the source arm of the OCT system, scanning laser ophthalmoscope (SLO) images can be recorded. Images of healthy and diseased human retinas are presented.
