Differences between Fresnel and Fraunhofer Diffractions

Fresnel  Diffraction
Fraunhofer Diffraction
The source and the screen are at finite distance from the diffracting aperture
The source and the screen are at infinite distance from the diffracting aperture
Near field diffraction
Far field diffraction
The wave fronts are divergent and are either spherical and cylindrical
The wave fronts are planar which is realized by using convex lenses
No mirror or lenses are used for observation
Diffracted light is collected by lens as in a telescope
