WebIn 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 diffraction pattern resulting from a uniformly-illuminated circular aperture has a bright region in the center, known as the Airy disk which together with the series of … WebThe central bright spot (fringe) is the "Airy disk". From Roy and Clarke's Astronomy: Principles and Practice. The minima for the Airy pattern actually occur at: Compare these to the fringe minima for the 1-d slit: We normally call the "size" of the Airy disk as that diameter across the Airy disk from minimum to minimum, or: origin of surname farlow
