a The image of a single fluorescent bead used as guide star. b The same scene as in (a) scrambled by the scattering layer indicating the PSF of the system. c The image of a fluorescent scene. d The same scene as in (c) scrambled after passing the same part of the turbid medium. e Reconstruction of the fluorescent scene seen in (c) by deconvoluting image (d) with image (b) using blind deconvolution with 80 iterations. The distance between the fluorescent sample and the scattering medium was set to 5 mm. All images are contrast-adjusted for better visibility as can be seen on individual colormap scales. The colormaps in parts (a) – (d) are scaled in 16-bit arbitrary units determined by the camera readout and represent the physically measured fluorescence intensity. The colormap in part (e) represents the mathematically calculated pixel values after deconvolution. The scale is normalized since the values vary depending on the number of iterations and the chosen algorithm. This holds true for the following figures as well
