Full-range complex spectral domain optical coherence tomography with arbitrary or unknown phase

Complex Spectral domain Optical Coherence Tomography (CSdOCT) produces images free of parasitic mirror component which results in twofold extension of the measurement range. Complete removal of this component requires exact knowledge of the introduced phase shifts, what is usually difficult to achieve. Presented method effectively removes the mirror image, even without the knowledge of the phases. The method is applicable to any variation of CSdOCT. The 'mirror image-free' tomograms of human anterior chamber in-vivo obtained with the aid of this approach are shown.
