Phase retrieval constitutes a pivotal challenge in disciplines ranging from optics and materials science to signal processing, where the objective is to reconstruct a signal’s phase from ...

Since their discovery by Roentgen in 1895, X-rays have become an effective tool for doctors to take images of their patients' bones, organs and vessels, and make better diagnoses. To date, scientists ...

Imaging objects that are partially or completely obscured by structures that diffuse the light from those objects, as is the case in many biological systems, is a challenge that engineers have met ...

For decades, imaging weakly scattering phase objects, such as cells, has been an active area of research across various fields, including biomedical sciences. One common approach uses chemical stains ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...
