    Single-Photon Technology Could Allow High-Sensitivity, Low-Power OCT

    A detection technology used in quantum optics also could be used to perform OCT (optical coherence tomography) with lower light power than previously possible, potentially improving the imaging quality available from OCT. “For clinical applications, being able to perform OCT with low light power is crucial because safety standards limit the light intensity levels that can be used,” research team leader Sylwia Kolenderska, from the University of Auckland, said. “In some cases, these power levels are not high enough to achieve good image quality.” While developing an OCT method based on quantum light, researchers at the University of Auckland discovered ...
