The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

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 ...

High-energy X-ray diffraction patterns from a single grain of i-Gd-Cd were taken at the Advanced Photon Source at Argonne National Laboratory with the beam parallel to the five-fold axis.

The electron diffraction pattern from iodine molecules depends on the distance between the two iodine nuclei, and changes as the molecule vibrates. Disclaimer: AAAS and EurekAlert! are not responsible ...

What do you do if you want to look inside a biological cell, hoping to see objects that are well beyond the diffraction limit of a microscope – roughly 200nm? One solution is to use the ...

Social Security's 2026 COLA Is Official: Retirees in These 10 States Will Get the Biggest Raises Ukrainian strikes disrupt power and heating to 2 major cities in Russia Can't-Miss Play: Wild fumble ...

Researchers have developed a new algorithm for recovering the 3D refractive index distribution of biological samples that exhibit multiple types of light scattering. Researchers have developed a new ...
