Abstract
We present what we believe to be a new computational algorithm for complex frequency domain
optical coherence tomography that can effectively suppress artifacts that are
caused by uncertainty in phase shift due to sample motion and 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 the numerical least-squares technique. A series of simulations and experiments prove that this algorithm can
effectively remove strong mirror-image artifacts because it is unaffected by random phase
fluctuation.
