Abstract

We present the first frequency-domain implementation of quantum optical coherence tomography, which eliminates the need for axial scanning, thus significantly speeding up data acquisition.

Capability of intensity-correlation spectral-domain optical coherence tomography

Tomohiro Shirai, Ari T. Friberg

We describe spectral-domain optical coherence tomography (OCT) based on classical intensity correlations. The setup employs a Hong-Ou-Mandel interferometer as a classical analogue of quantum OCT. It is shown theoretically that it enables scanless cross-sectional imaging with dispersion cancellation and axial resolution enhancement. Some basic features of the technique are addressed.

Quantum-Optical Coherence Tomography with Collinear Entangled Photons

We demonstrate the implementation of collinear entangled photons for Quantum-Optical Coherence Tomography using a Michelson interferometer. Compared to the standard configuration, based on the Hong-Ou-Mandel interferometer, our method offers robustness and adaptability.

Fourier domain quantum optical coherence tomography

Sylwia M. Kolenderska, Frédérique Vanholsbeeck, Piotr Leszek Kolenderski

Quantum optical coherence tomography (Q-OCT) is the non-classical counterpart of optical coherence tomography (OCT), a high-resolution 3D imaging technique based on white-light interferometry. Because Q-OCT uses a source of frequency-entangled photon pairs, not only is the axial resolution not affected by dispersion mismatch in the interferometer but is also inherently improved by a factor of two. Unfortunately, practical applications of Q-OCT are hindered by image-scrambling artefacts and slow acquisition times. Here, we present a theoretical analysis of a novel approach that is free of these problems: Fourier domain Q-OCT (Fd-Q-OCT). Based on a photon pair coincidence detection as in the standard Q-OCT configuration, it also discerns each photon pair by their wavelength. We show that all the information about the internal structures of the object is encoded in the joint spectrum and can be easily retrieved through Fourier transformation. No depth scanning is required, making our technique potentially faster than standard Q-OCT. Finally, we show that the data available in the joint spectrum enables artefact removal and discuss prospective algorithms for doing so.

Experimental demonstration of full-field quantum optical coherence tomography

Zeferino Ibarra-Borja, Carlos Sevilla-Gutiérrez, Roberto Ramírez-Alarcón +2 more

We present, to the best of our knowledge, the first implementation of full-field quantum optical coherence tomography (FF-QOCT). In our system, we are able to obtain full three-dimensional (3D) information about the internal structure of a sample under study by relying on transversely resolved Hong–Ou–Mandel (HOM) interferometry with the help of an intensified CCD (ICCD) camera. Our system requires a single axial scan, obtaining full-field transverse single-photon intensity in coincidence with the detection of the sibling photon for each value of the signal-idler temporal delay. We believe that this capability constitutes a significant step forward toward the implementation of QOCT as a practical biomedical imaging technique.

Spectral-Domain Quantum OCT with Frequency Scanning: Theoretical Proposal

Tatiana Makovetskaya, Nikolai A. Ushakov

The aim of this work is to develop a spectral-domain quantum optical coherence tomography approach, based on the control of the joint spectral amplitude of the entangled photons. 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 of digital processing of an interference signal on the achievable axial spatial resolution was shown. The influence of the shape of the joint spectral amplitude of the entangled photons on the final interference signal was analyzed, and the possibility of improving the quality of the interference signal by controlling the properties of the spectral amplitude was considered.
