Pixel hopping enables fast STED nanoscopy at low light dose

Authors Vinçon B, Geisler C, Egner A Journal Optics Express Citation Opt. Express 28, 4516-4528 (2020). Abstract The achievable image quality in fluorescence microscopy and nanoscopy is usually limited by photobleaching. Reducing the light dose imposed on the sample is thus a challenge for all these imaging techniques. Various approaches
