Synthetic aperture radar interferometry or InSAR is a technique where two or more satellite radar images acquired over the same area are combined to produce an interferogram.
OCT interferogram is obtained by moving the position of the reference mirror changing the reference path by a certain amount ([DELTA]z) to match multiple sample optical structure and a depth profile (A-Scan) of the sample can be acquired [1].
