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. The Airy disk is of importance in physics, optics, and astronomy. The diffraction pattern resulting from a uniformly … See more Far from the aperture, the angle at which the first minimum occurs, measured from the direction of incoming light, is given by the approximate formula: or, for small angles, … See more The intensity of the Airy pattern follows the Fraunhofer diffraction pattern of a circular aperture, given by the squared modulus of the Fourier transform of the circular aperture: See more Similar equations can also be derived for the obscured Airy diffraction pattern which is the diffraction pattern from an annular aperture or beam, i.e. a uniform circular aperture (beam) obscured by a circular block at the center. This situation is relevant to many … See more Cameras If two objects imaged by a camera are separated by an angle small enough that their Airy disks on … See more Light from a uniformly illuminated circular aperture (or from a uniform, flattop beam) will exhibit an Airy diffraction pattern far away from the … See more The Airy pattern falls rather slowly to zero with increasing distance from the center, with the outer rings containing a significant portion of the integrated intensity of the pattern.

Introduction. The circular Airy beam (CAB) has attracted intensive interest since it is first proposed in 2010 [1], [2].The multiple rings of CAB focus along parabolic trajectory in free space, leading to the unique abruptly autofocusing property [3].CAB could keep a low intensity before the focal point and form a sharp light spot in the focal region, therefore it …

The term "Airy beam" derives from the Airy integral, developed in the 1830s by Sir George Biddell Airy to explain optical caustics such as those appearing in a rainbow. The Airy waveform was first theorized in 1979 by M. V. Berry and Nándor L. Balázs. They demonstrated a nonspreading Airy wave packet solution to the Schrödinger equation.
