Angular resolution describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution. It is used in optics applied to light waves, in antenna theory applied to radio waves, and in acoustics applied to sound waves. The colloquial use of the term … WebAnother criterion that is occasionally utilized instead of the axial Rayleigh criterion is the full width at half maximum (FWHM) of the central bright region of the point spread …

WebTo obtain a good image, point sources must be sufficiently far apart that their diffraction patterns do not overlap. The famous Rayleigh criterion describes the minimum distance … WebThis calculator is based on the Rayleigh criterion, which states that the Airy disks should be at least one radius apart. The radius of an Airy disk is the distance from the center to the first zero. Mathematically, the minimum angle that can be resolved based on this criterion is. \alpha = \dfrac {1.22 \lambda} {D} α = D1.22λ.
