description: The given work is to the development of an approach to spectral quantum optical coherence tomography based on the control of the joint spectral distribution of entangled photons. In this work, an analytical expression is obtained that describes the signal of spectral quantum optical coherence tomography. The dependence of the interference signal on the change in the difference between the central frequencies of the spectral distributions of entangled photons was demonstrated. The effect on the signal of the uncertainty condition of the frequency at which the photon enters which of the arms of the interferometer, and the change in the signal when this condition is violated, were studied. The effect of digital processing of an interference signal on the limitation of the minimum resolvable thickness of a layer studied using spectral optical coherence tomography was shown. The influence of the shape of the joint spectral distribution of photons on the final interference signal was analyzed, and the possibility of improving the quality of the received signal by controlling the properties of the spectral distribution was considered.
