Difference between Diffraction and Speckle pattern

Diffraction vs. Speckle pattern

--> Diffraction refers to various phenomena that occur when a wave encounters an obstacle or a slit. A speckle pattern is an intensity pattern produced by the mutual interference of a set of wavefronts.

Similarities between Diffraction and Speckle pattern

Diffraction and Speckle pattern have 9 things in common (in Unionpedia): Airy disk, Fraunhofer diffraction, Fresnel diffraction, Holography, Isaac Newton, Laser, Near and far field, Wave interference, Wavelength.

Airy disk

In optics, the Airy disk (or Airy disc) and Airy pattern are descriptions of the best focused spot of light that a perfect lens with a circular aperture can make, limited by the diffraction of light.

Fraunhofer diffraction

In optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when the diffraction pattern is viewed at a long distance from the diffracting object, and also when it is viewed at the focal plane of an imaging lens.

Fresnel diffraction

In optics, the Fresnel diffraction equation for near-field diffraction is an approximation of the Kirchhoff–Fresnel diffraction that can be applied to the propagation of waves in the near field.

Isaac Newton

Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English mathematician, astronomer, theologian, author and physicist (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time, and a key figure in the scientific revolution.

Laser

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.

Near and far field

The near field and far field are regions of the electromagnetic field (EM) around an object, such as a transmitting antenna, or the result of radiation scattering off an object.

Wave interference

In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude.

Wavelength

In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
