WebJan 1, 2011 · Airy disc is merely a geometric term related to the diffraction image produced by a clear aberration-free aperture (specifically, the disc limited by the first minima of such aperture). The image formed by the otical train IS the 2 Dimensional Convolution of the incoming complex wave and the Point Spread function of the optical train. WebDiffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the …

WebThis yields a blurred spot at the focal point. Light near the focal point exhibits an Airy Disc pattern. The size of the Airy Disc is determined by the focal length f and diameter D of the lens. Since the spreading angle is θ ~ r/f, the radius r of the Airy Disc at the focal point of a lens is given by r = 1.22λf/D. http://zeiss-campus.magnet.fsu.edu/tutorials/basics/airydiskbasics/index.html
