Organizing and summarizing search results for youFraunhofer and Fresnel diffraction are two concepts in optics:- Fraunhofer diffraction occurs when plane waves are incident on a diffracting object, and the diffraction pattern is viewed at a sufficiently long distance from the object (in the far-field region).
- Fresnel diffraction deals with the more general case where the source of light and the screen on which the pattern is observed are not effectively at infinite distances from the aperture causing the diffraction.
