diffraction pattern

noun

1. physics the distinctive pattern of light and dark fringes, rings, etc, formed by diffraction

diffraction pattern

1. The interference pattern that results when a wave or a series of waves undergoes diffraction, as when passed through a diffraction grating or the lattices of a crystal. The pattern provides information about the frequency of the wave and the structure of the material causing the diffraction.
2. See also interferometer

Example Sentences

One PSF basically describes how an infinitely small point source of light originating in the sample is widened and spread into a three-dimensional diffraction pattern by the optical system.

From Science Daily

"A typical diffraction pattern would produce evenly spaced fringes if we just had a neutron star as a shield," the KU researcher said.

From Science Daily

The primary mirror shape creates a six-pointed diffraction pattern for sufficiently bright sources: each “spike” in this pattern stretches toward one of the points of a hexagon.

From Scientific American

Whereas the crystallographic restriction theorem asserted that crystals can possess only two-, three- four- or sixfold rotationally symmetry, the Bragg diffraction pattern of quasicrystals shows other symmetry orders—such as a fivefold symmetry.

From Scientific American

The key piece of evidence, ‘Photograph 51’, showed the diffraction pattern of DNA and was taken, under the supervision of crystallographer Rosalind Franklin, by then-graduate student Raymond Gosling16.
