Comparison of two reconstruction strategies with different illumination bandwidths. (a) Ground truth phase image of a synthetic sample generated from a chip design file; (b) an example probe at the central wavelength (8.8 keV) in the simulation; (c) source spectrum with a Gaussian distribution of 1% bandwidth, the red dots indicate the five wavelengthes used in multi-wavelength reconstruction; (d)–(g) reconstructed phase images for bandwidth of 1%, 2%, 5%, 10%, respectively; images on the top show the results using the mixed-state approach while those at the bottom show the corresponding results using the multi-wavelength method. The normalized reconstruction error E is shown on each reconstructed image.
