From: Ultra-broadband ptychography for dispersive samples

Fig. 4

The results of the 1.8% bandwidth source combined with traditional ptychography are used as the benchmark for comparison, followed by the processing and comparison of diffraction data from the 15% bandwidth source using monochromatized ptychography and ultra-broadband ptychography, respectively. a Reconstruction of an amplitude-type USAF resolution target. b Reconstruction of an unstained ant specimen. c Reconstruction of a freshwater copepod sample. The yellow circle indicates an empty region, the green circle marks the Fast Green–stained sample region, and the orange dashed circle denotes the Eosin-stained sample region. The scale bar in (a) corresponds to 200 μm; the scale bar in (b) corresponds to 300 μm and the scale bar in (c) corresponds to 400 μm.
