Quantum Optical Coherence Tomography (Q-OCT) uses quantum properties of light\nto provide several advantages over its classical counterpart, OCT: it achieves\na twice better axial resolution with the same spectral bandwidth and it is\nimmune to even orders of dispersion. Since these features are very sought-after\nin OCT imaging, many hardware and software techniques have been created to\nmimic the quantum behaviour of light and achieve these features using\ntraditional OCT systems. The most recent, purely algorithmic scheme - an\nimproved version of Intensity Correlation Spectral Domain OCT named ICA-SD-OCT\nshowed even-order dispersion cancellation and reduction of artefacts. The true\ncapabilities of this method were unfortunately severely undermined, both in\nterms of its relation to Q-OCT and in terms of its main performance parameters.\nIn this work, we provide experimental demonstrations as well as numerical and\nanalytical arguments to show that ICA-SD-OCT is a true classical equivalent of\nQ-OCT, more specifically its Fourier domain version, and therefore it enables a\ntrue two-fold axial resolution improvement. We believe that clarification of\nall the misconceptions about this very promising algorithm will highlight the\ngreat value of this method for OCT and consequently lead to its practical\napplications for resolution- and quality-enhanced OCT imaging.\n
