Fig. 5: Extraction of the spectrum and broadband phase retrieval.

From: Towards attosecond imaging at the nanoscale using broadband holography-assisted coherent imaging in the extreme ultraviolet

Fig. 5

a The average of five cross-correlations of two reference apertures each. b, c The lineouts of the averaged cross-correlation terms, which are averaged over the vertical and horizontal axis. d Spectrum obtained by deconvolving b with c, which is compared to the measured spectrum (orange). e Reconstructed object after applying a broadband, iterative phase retrieval algorithm on the measured diffraction pattern with Fig. 3e as the initial field and Fig. 5d as input spectrum. The scale bar in e corresponds to 1 µm. The amplitude and spectral intensity is given in arbitrary units (a.u.).
