A new optical coherence angiography (OCA) method, called correlation mapping OCA (cmOCA), is presented by
using the SNR-corrected complex correlation. An SNR-correction theory for the complex correlation calculation
is presented. The method also integrates a motion-artifact-removal method for the sample motion induced
decorrelation artifact. The theory is further extended to compute more reliable correlation by using multi-
channel OCT systems, such as Jones-matrix OCT. The high contrast vasculature imaging of in vivo human
posterior eye has been obtained. Composite imaging of cmOCA and degree of polarization uniformity indicates
abnormalities of vasculature and pigmented tissues simultaneously.
