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 ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...

X-ray diffraction (XRD) is a powerful non-destructive analytical technique used to evaluate crystalline materials and determine their structural properties. As one of the most widely used ...
