Chalk sample tomographic reconstruction. (a) Phase retrieved projection using pure-phase algorithms. (b) 3D reconstructed slice marked by the red line in (a). (c) 3D rendering of the chalk sample. (d) Fourier shell correlation results and resolution estimation, where the vertical orange-dashed line represents the focal-spot resolution limit. The scale bars correspond to 2 µm, and the resolution estimated by the half-bit threshold criterion is 155 nm. |
