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. As a result, … See more • Amateur astronomy • Apodization • Fraunhofer diffraction • Bloom (shader effect) See more WebDec 23, 2024 · Abstract: A new type of circular Airy beams is demonstrated by using a bandpass filter, in order to enhance the field intensity at the focal point of light beam, …
