Diffraction in a sentence

A diffraction pattern of a 633 nm laser through a grid of 150 slits Diffraction grating main A diffraction grating is an optical component with a regular pattern.

Several qualitative observations can be made of diffraction in general: *The angular spacing of the features in the diffraction pattern is inversely proportional to the dimensions of the object causing the diffraction.

A diffraction-limited lens is one in which aberrations have been reduced to the point where the image quality is primarily limited by diffraction under the design conditions.

Although electron, neutron, and X-ray scattering are based on different physical processes, the resulting diffraction patterns are analyzed using the same coherent diffraction imaging techniques.

Although this is counterintuitive, the prediction is correct; in particular, electron diffraction and neutron diffraction are well understood and widely used in science and engineering.

A very large reflecting diffraction grating An incandescent light bulb viewed through a transmissive diffraction grating.

Because of this, the powder diffraction method, which uses diffraction patterns of polycrystalline samples with a large number of crystals, plays an important role in structural determination.

Calculation of diffraction images To calculate the full diffraction image that is visible on the screen one has to consider the surface integral of the previous section.

Comparison of the spectra obtained from a diffraction grating by diffraction (1), and a prism by refraction (2).

Determining combined defocus and diffraction Hansma (1996) and Peterson (1996) have discussed determining the combined effects of defocus and diffraction using a root-square combination of the individual blur spots.

Diffraction main A wave exhibits diffraction when it encounters an obstacle that bends the wave or when it spreads after emerging from an opening.

Diffraction of light Some examples of diffraction of light are considered below.

History Diffraction of a plane wave at a slit whose width is several times the wavelength Diffraction of a plane wave when the slit width equals the wavelength In 1678, Huygens Chr.

James Gregory (1638–1675) observed the diffraction patterns caused by a bird feather, which was effectively the first diffraction grating to be discovered.

The bond lengths R(AB) are measured by X-ray diffraction (more rarely, neutron diffraction on molecular crystals ).

The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disk.

These gratings, called volume phase holography diffraction gratings (or VPH diffraction gratings) have no physical grooves, but instead a periodic modulation of the refractive index within the gel.

There are also many applications for this technology in AR devices that already utilize diffraction gratings as a key component.

Is the uncertainty principle applicable to single slit diffraction?

The first dataset was X-ray diffraction data from 15 types of homo-polypropylenes subjected to a range of temperatures, and the second was data from four types of homo-polypropylenes that underwent injection molding.
