Hyperspectral Mid-Infrared Imaging With Undetected Photons
…Taking advantage of the quantum optical effect of “sensing with undetected photons”, researchers at Humboldt University in Berlin and FBH-Berlin, in collaboration with Fraunhofer IPM Freiburg, have now developed a spectral imaging method that transfers the measurement of molecular mid-infrared fingerprints of biological and industrial samples to the detection range of silicon-based cameras.…
