Dose Constraints for High-Resolution Imaging of Biological Specimens with Extreme Ultraviolet and Soft X-ray radiation
Chang Liu, Leona Licht, Jan Rothhardt
We present a theoretical evaluation of radiation dose constraints for extreme ultraviolet (EUV) and soft X-ray microscopy. Our work particularly addresses the long-standing concern…

Bayesian multi-exposure image fusion for robust high dynamic range ptychography
Shantanu Kodgirwar, Lars Loetgering, Chang Liu +6
The limited dynamic range of the detector can impede coherent diffractive imaging (CDI) schemes from achieving diffraction-limited resolution. To overcome this limitation, a straig…
