We describe a resolution-improved spectral-domain (SD) optical coherence tomography (OCT) based on classical intensity correlations as a counterpart of the recently proposed intensity-based time-domain OCT. Similarly to quantum OCT, the setup employs the Hong-Ou-Mandel interferometer at the output of the conventional SD-OCT. It is shown theoretically that a factor-of-2 improvement in axial resolution is obtained with this arrangement. Some unique and useful features of our proposed system are addressed.
