Abstract :
In this research, we demonstrated a phase-resolved optical coherence tomography (OCT) system that uses optical Hilbert transformation. We simultaneously measured two interference signals that had a 90deg phase difference. By this method, a phase-contrast tomographic image can be obtained.
