Video-Rate Imaging with Undetected Photons

Imaging and microscopy are some of the most important tools in modern life science for getting new insights into metabolisms or unravelling bio-chemical processes. However, in particular low-light observations outside the visible spectrum are still challenging and a limiting factor. A rugged, label-free quantum imaging system is presented capable of recording at video rate in the visible regime, while illuminating the sample with undetected light of different wavelength. The results pave the way for a field deployable quantum imaging device allowing live-cell imaging in extreme spectral ranges with a minimal photo dose.
