Figure Lengend Snippet: (a) Testbench for joint simulation-experimental pipeline for image reconstruction in a multichannel UHD-DOT scheme. (b) Geometry of the experimental and simulation arrangement. A square array of high-density laser point sources (bottom, red) and the CMOS detector camera chip (top, blue) are separated by 12 mm thickness (equivalent of 60 photon mean free paths) turbid media. A target object of interest (a 1mm diameter sphere in this illustration) is immersed in the middle of the densely scattering medium.
