Coherent diffraction imaging (CDI) is a powerful method for visualizing the structure of an
object with a high spatial resolution that exceeds the performance limits of the lens. Single …

Nanoscale coherent imaging has emerged as an indispensable modality, allowing to
surpass the resolution limit given by classical imaging optics. At the same time, attosecond …

Phase retrieval is a numerical procedure concerned with the recovery of a complex-valued
signal from measurements of its amplitude. We describe a generalization of this method for …

Ultrafast lasers, providing the shortest pulses worldwide, have been playing a vital role in
the ultrafast imaging technology. The temporal resolution has been increasing rapidly in …

Ultrafast imaging simultaneously pursuing high temporal and spatial resolution is a key
technique to study the dynamics in the microscopic world. However, the broadband spectra …

Diffraction before destruction1, 2 has been a key vision driving the development and
