Fast holographic scattering compensation for deep tissue biological imaging
Nature Communications, 2021 Wavefront shaping is used to overcome scattering in biological tissues during imaging, but determining the compensation is slow. Here, the authors use holographic phase stepping interferometry, where new phase information is updated after each ...
