Fresnel diffraction
Definición
- In 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 the diffraction pattern in the far field region is given by the Fraunhofer diffraction equation. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Fresnel_diffraction)
