What (who) is Laue diffraction pattern - definition

FAR-FIELD DIFFRACTION

Far-field diffraction pattern; Fraunhofer diffraction pattern; Fraunhoffer diffraction; Fraunhofer Diffraction; Fraunhofer limit; Frauenhofer Diffraction; Fraunhofer's Diffraction; Fraunhofer diffraction theory; Frauhoffer diffraction

$Computer simulation of the Airy diffraction pattern$
$Diffraction of a laser beam by a grating$
$Diffraction glass with 300 lines per milimeter$
$A geometrical diagram used to derive Fraunhofer condition at which Fraunhofer diffraction is valid.$
$Example of far field (Fraunhofer) diffraction for a few aperture shapes.$
$Computer simulation of Fraunhofer diffraction by a rectangular aperture$

Diffraction from slits

$Numerical approximation of diffraction pattern from a slit of width equal to wavelength of an incident plane wave in 3D blue visualization$

Kinematic theory of diffraction; Diffraction formalism

Diffraction processes affecting waves are amenable to quantitative description and analysis. Such treatments are applied to a wave passing through one or more slits whose width is specified as a proportion of the wavelength.

Fraunhofer diffraction

In optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when plane waves are incident on a diffracting object, and the diffraction pattern is viewed at a sufficiently long distance (a distance satisfying Fraunhofer condition) from the object (in the far-field region), and also when it is viewed at the focal plane of an imaging lens.Born & Wolf, 1999, p.

Pattern (casting)

FORM USED IN CASTING TO REPLICATE A SHAPE

Pattern (foundry); Pattern-maker; Patternmaker (engineering)

In casting, a pattern is a replica of the object to be cast, used to prepare the cavity into which molten material will be poured during the casting process.

Fraunhofer diffraction

In optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when plane waves are incident on a diffracting object, and the diffraction pattern is viewed at a sufficiently long distance (a distance satisfying Fraunhofer condition) from the object (in the far-field region), and also when it is viewed at the focal plane of an imaging lens. In contrast, the diffraction pattern created near the diffracting object and (in the near field region) is given by the Fresnel diffraction equation.

The equation was named in honor of Joseph von Fraunhofer although he was not actually involved in the development of the theory.

This article explains where the Fraunhofer equation can be applied, and shows Fraunhofer diffraction patterns for various apertures. A detailed mathematical treatment of Fraunhofer diffraction is given in Fraunhofer diffraction equation.
