Fig. 5: Super-resolution and super-speed compressive endo-microscopy through the MM fibre with NA = 0.1.

a, b Images of two fluorescent spheres through the MM fibre probe obtained by a the proposed super-resolution compressive endo-microscopy and b the state-of-the-art raster scan wavefront shaping-based endo-microscopy. c Cross-sectional plots along the dashed lines in (a open red circles) and (b open blue triangles). The blue line is a Gaussian fit to the data, and the red line interpolates the data. d Resolution of compressive endo-microscopy as a function of the total number of measurements averaged over four fluorescent spheres. The error bars represent the standard deviation. The diffraction limit is represented by the solid green line
