Figure 5
Broadband ptychography using different beam sizes. The probe size was changed by placing the sample at different defocus positions. Panels (a)–(d) show ptychography reconstructions of a dataset acquired with a ∼500 nm illumination of 1% bandwidth, using single-mode (a), mixed-state approach (b), multi-wavelength approach (c). The reconstructed five spectral probe modes are shown in (d). Panels (e)–(h) are corresponding reconstructions using a 1.5 µm illumination size.
