KnowraFresnel diffractionLinked fromLinked fromThe 9 pages that link to Fresnel diffraction, each with the reason it gives.All 9Broader topic 3Related 5Compared with 1DiffractionBroader topic: It describes patterns close to an opening, where the far-field approximation fails.Huygens–Fresnel principleBroader topic: The principle provides a direct way to calculate this near-field pattern.HolographyBroader topic: Many hologram recordings and reconstructions depend on propagation through the near field.Fraunhofer diffractionCompared with: It retains propagation effects omitted in the Fraunhofer approximation.Paraxial approximationRelated: Its propagation integral follows from the paraxial form of the wave equation.Fourier opticsRelated: Its paraxial propagation integral becomes a Fourier-transform relation with quadratic phase factors.Stellar occultationRelated: Diffraction shapes the starlight pattern at the occulting body's shadow edge.Fresnel integralsRelated: Its field amplitudes are expressed through differences of Fresnel integrals.Fresnel numberRelated: The Fresnel number indicates when this regime’s finite-distance effects matter.
