Fraunhofer Diffraction Diagram
Experimental setup for a diffraction pattern experiment. In optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when the diffraction pattern is viewed at a long distance from the diffracting object (in the far-field region), and also when it is viewed at the focal plane of an imaging lens. In contrast, the diffraction pattern created near the object (in the near field region) is given by the Fresnel diffraction equation.
