Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

The demonstrated QCMs can reconstruct holographic images and display diffraction patterns simultaneously. Silicon nanofins are arranged in the Penrose tiling pattern as illustrated by the 2D color ...

2D-XRD, or two-dimensional X-ray diffraction, is a powerful analytical technique used to study the atomic and molecular structure of crystalline materials at the nanoscale. It provides detailed ...

XRD works by directing X-rays onto a crystalline material and analyzing the angles and intensities of the diffracted beams. The atomic planes within the crystal act as a three-dimensional grating, ...

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 ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...
