WebIn optics, the Fresnel diffraction equation for near-field diffraction is an approximation of the Kirchhoff–Fresnel diffraction that can be applied to the propagation of waves in the near field. It is used to calculate the diffraction pattern created by waves passing through an aperture or around an object, when viewed from relatively close to the object. In contrast … WebA plate is now placed at $ z = 0 $ with an opening $ S '$.

WebWhen the Fresnel-Kirchhoff (FK) diffraction integral is evaluated exactly (instead of using the Fresnel approximation), the well-known mathematical inconsistency in the FK boundary conditions leads to unacceptable results for the intensity of Poisson’s spot. The Rayleigh-Sommerfeld (RS) integral doesn’t have this problem. According to the Rayleigh-Sommerfeld diffraction theory, the electric-field diffraction pattern at a point (x, y, z) is given by where is the electric field at the aperture, , is the wavenumber , is the imaginary unit.
