Fresnel diffraction

1. Also known as near-field diffraction. The field of radiation sent through an aperture in an absorbing screen at large distances as compared with the wavelength and the dimensions of the aperture, but small enough to necessitate consideration of the effect of the phase differences between secondary wavelets. 2. The effect of diffraction obtained when the source of radiation and/or the observing screen are at a finite distance from the diffraction aperture or obstacle.
