Abstract

We analyze the resolution limit that can be achieved by means of spectral reshaping in optical coherence tomography images and demonstrate that the resolution can be improved by means of modelessly reshaping the source spectrum in postprocessing. We show that the optimal spectrum has a priory surprising "crater-like" shape, providing 0.74 micron axial resolution in free-space. This represents ∼50% improvement compared to resolution using the original spectrum of a white light lamp.
