Phase and absorbance retrieval from a hard X-ray hologram. (a) Intensity map of the X-ray hologram and (b) scanning electron microscope image of the target sample. (c) In-focus hologram reconstructed using the angular spectrum method. (d–f) Phase shift maps reconstructed by the Gerchberg–Saxton (GS) algorithm, residual U-Net (ResUNet), and MorpHoloNet-X. (g–i) Absorbance maps reconstructed by the GS algorithm, ResUNet, and MorpHoloNet-X. Scale bars are 1 µm.
