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 ...

Figure 1： The flowchart of ACDPC iterative reconstruction joint optimization algorithm. (a) ACDPC imaging system based on half-annular illumination. (b) Three annular illumination patterns and their ...

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 ...

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 ...

In a study published in Photonics Research, researchers from Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) has proposed a new scheme for single-shot ...

Ptychography is an imaging method that applies algorithms to the diffraction patterns formed when an object is illuminated by coherent light, potentially removing the need for a focusing lens when ...
