Difference Between Fresnel Diffraction And Fraunhofer Diffraction

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
For obtaining fresnel diffraction , zone plates are used	For this single double ae plane diffraction grating are used
The wavefronts are divergent either spherical and cylindrical	The wavefronts are plane which is released by using convex lens
No mirror or lenses are used for observation	Diffracted light is collected by lens as in telescope
