Diffraction phenomenon is broadly classified into two categories: (a) Fresnel diffraction (near-field diffraction) The interference is considered to take place from different parts of an aperture when either the source or screen or both are at finite distance from the obstacle.
(b) Fraunhoffer diffraction (far-field diffraction) The interference is considered to take place from different parts of an aperture when either the source or screen or both are at finite distance from the obstacle.
