Artifacts removal in complex frequency domain optical coherence tomography with numerical least-square phase-shifting algorithm

Research output: Contribution to journal › Conference article › peer-review

Abstract

We present a new computational algorithm for complex frequency domain optical coherence tomography (FD-OCT) that can effectively suppress artifacts, which are caused by uncertainty in phase shift due to errors in reference phases. The algorithm treats the phase shifting values as additional unknowns and we can determine their exact values by analyzing interference fringes using numerical least square technique. A series of simulation and experiments prove that this algorithm can effectively remove strong mirror image artifacts because it is unaffected by random phase fluctuation.
