dc.description.abstractCurrent research aims to exploit the quantum properties of light for the improvement of classical imaging techniques. Quantum Optical Coherence Tomography (QOCT) is a promising non-invasive technology that leverages quantum entanglement to enhance the resolving power of classical Optical Coherence Tomography (OCT) by a factor of two. This technique offers immunity to chromatic dispersion and the capability to deliver high-resolution images even under ultra-low light intensities. Despite these advantages, QOCT faces challenges in terms of long acquisition times during measurements, and the presence of artifacts—spurious structures that corrupt the signal and disrupt the extraction of information. Our research focuses on addressing the latter challenge. We propose two experimental methods, both based on the manipulation of the pump and state of entangled photons, to eliminate artifacts from the signal. The first method involves tuning the pump laser wavelength to manipulate the visibility of artifacts and the overall profile of the resulting interferograms. Additionally, we introduce a novel and comprehensive theoretical model that describes the appearance and behavior of artifacts, along with newly discovered features referred to as ”echoes.” The second method suggests introducing an external phase into the entangled source to influence the state of the biphotons and further manipulate the shape of the artifacts. Our methods are both experimentally simple and effective, positioning QOCT as a commercially viable and practical imaging device.
