1. A method of analyzing optical coherence tomography data, said method comprising: acquiring a data set using an optical coherence tomography (OCT) system, said data set comprising a plurality of measurements of a sample, wherein the data set contains at least two measurements that were made at approximately the same location on the sample; processing the OCT data set to generate complex OCT signals, wherein the complex signal can be described by an intensity and a phase; normalizing the complex OCT signals; after normalizing the complex OCT signals generating motion contrast information by taking the difference between at least two normalized complex OCT signals corresponding to OCT measurements acquired at approximately the same location on the sample; and storing or displaying the resulting motion contrast information.
