In this regard, Prof. Paul-Antoine Moreau from QFort-NCKU and his colleagues from the University of Glasgow and the Max Plank institute proposed a full-field in-phase imaging system.

While low-light imaging hasbecome crucial in many areas,applications are still limited to thevisible region of the spectrumwhere detector noiseperformance is favorable.We present a full-field, homodyneimaging system capable ofimaging at the single-photonlevel in the shortwave infrared,despite the camera having anoise floor≈200 times higher.This interference approach tolow-light imaging was firstsuggested by Gabor 70 y ago.Our approach requires only asingle camera frame, unlike othertemporally based interferencemethods which require temporalscanning. While extending thecapacity of holographicmicroscopes, our demonstrationwill also extend the range ofapplications of low-light imaging,benefiting biological, medical, andcovert imaging.
