Paper Abstract
We propose a maximum a-posteriori (MAP) intensity estimator to improve the image contrast of polarization diversity
(PD)-OCT imaging to achieve high contrast polarization-artifact-free images. The MAP estimator compensates for the
inevitable reduction of signal-to-noise ratio (SNR) in PD-OCT caused by the splitting of power into two polarization
detection channels. It also has low noise-offset in low intensity regions such as the vitreous. This method is applied to
posterior eye images, and shows high-contrast, polarization-artifact-free images. This method also enables attenuation
coefficient imaging with finer differentiation of attenuation levels.
