摘要

Quantum optical coherence tomography (QOCT) is a promising approach to overcome the degradation of the resolution in optical coherence tomography (OCT) due to dispersion. Here, we report on an experimental demonstra-tion of QOCT imaging in the high-resolution regime. We achieved a depth resolution of 2.5 mu m, which is the highest value for QOCT imaging, to the best of our knowledge. We show that the QOCT image of a dispersive material remains clear whereas the OCT image is drastically degraded. (c) 2022 Optica Publishing Group
