When the conventional optical coherence tomography (OCT) measures the transmittance and the absorbance of the target in the scattering media, its image is affected by the scattering media and gets a modulated target profile. Due to the influence of s

An optical coherence tomography (OCT) system based on the ghost imaging (GI) technique is developed for correctly imaging in scattering media. Usually, the scattering in the media leads to a decrease in the signal-to-noise ratio of the reconstructed
