When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

In the field of scanning electron microscopy (SEM), the electron backscatter diffraction (EBSD) method has developed into a robust tool for the crystallographic analysis of materials. Specifically, ...

Using ultrahigh-intensity x-ray beams can cause the intensity of diffraction patterns from samples to drop Figure 1: An x-ray diffraction pattern obtained from a sample of Martian soil. X-ray ...

The (relatively) ancient art of crystallography has had a huge impact on modern science by showing us the location of atoms within a molecule. The structure of DNA (and how it acts as an information ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

Particle size analysis is crucial to quality control and product development in a number of key industries including aerosols, construction, food and beverage, paint and coatings, and pharmaceuticals.

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is ...

A material that is capable of the “reverse diffraction” of light and that is inspired by butterfly wings has been made by researchers in the US. The structure combines features of the butterfly’s ...
