Extended Data Fig. 4: Ablation study on ground truth data for 3μm polystyrene beads.

The proposed network was trained with whole diffraction intensity data (3600 patches) while decreasing the portion of the complex amplitude data as 100%, 10%, 1%, and 0.5%. a,b, The diffraction intensity measured at (a) 9 mm and (b) 15 mm are used as the network input. The proposed approach consistently generates the complex amplitude maps up to the level where 1% (~60 patches) of complex amplitude data are used for training. Scale bar: 20 μm.
