Resolution-matched gain in Multi-beam ptychography
Runqing Yang, Maik Kahnt, Pablo Villanueva-Perez
Single-beam ptychography (SBP) requires overlapping scan positions for reliable reconstruction, and imaging larger areas demands more measurements. Multi-beam ptychography (MBP) il…

4D reconstruction of alumina laser melt pools at 25 kHz via operando X-ray multi-projection imaging
Lars Witte, Eliot Jermann, Zhe Hu +9
Advancing additive manufacturing, e.g., laser powder-bed fusion (LPBF), requires resolving rapid processes such as melt-pool dynamics and keyhole evolution in 4D (3D + time). Opera…
