KnowraFraunhofer diffractionLinked fromLinked fromThe 11 pages that link to Fraunhofer diffraction, each with the reason it gives.All 11Broader topic 3Related 2Narrower topic 2Compared with 4DiffractionBroader topic: This approximation yields compact formulas for patterns observed far from an aperture.Diffraction limitRelated: Its aperture patterns provide the standard basis for calculating optical resolution.Fraunhofer linesCompared with: It shares Fraunhofer’s name but describes wave diffraction, not solar absorption lines.Huygens–Fresnel principleBroader topic: It follows from the same wavefront construction under far-field approximations.Rayleigh criterionNarrower topic: The criterion compares far-field patterns from two point sources.Plane waveRelated: Far-field illumination and observation are commonly represented with plane waves.Airy diskNarrower topic: The Airy disk is the circular-aperture case of this far-field pattern.Fourier opticsBroader topic: In the far field, the diffraction pattern is proportional to the aperture's Fourier transform.Fresnel diffractionCompared with: It is the limiting regime where Fresnel curvature effects become negligible.Fresnel integralsCompared with: Unlike Fresnel diffraction, it replaces the quadratic phase with a simpler far-field limit.Fresnel numberCompared with: Its approximation contrasts with finite-distance Fresnel diffraction, but this page links it under mechanism.
