Airy Disk

In space and astronautical engineering, Airy Disk refers to the bright circular central region of the point spread function of a star or any other astronomical object that is imaged through a telescope. It is caused by diffraction of light as it passes through the telescope's aperture. The size of the Airy Disk is determined by the diameter of the telescope's aperture and the wavelength of the light being observed. The Airy Disk is important in determining the resolution of a telescope, as it sets a fundamental limit on the smallest resolvable features in an image. In addition, the shape and size of the Airy Disk can provide information about the properties of the object being observed, such as its brightness and size.
