Abstract
We propose a new multi-focus average method for optical coherence tomography, to reduce the multiple scattering signals and improve the visibility of the sample structure in the deep region. It combines computational refocusing, complex averaging, and multiple acquisitions with focal shifting. A scattering phantom was measured to validate the suppression of multiple scattering signals and the contrast improvement at the deep region.
