"In optics, the Fresnel diffraction equation for near-field diffraction is an approximation of the Kirchhoff–Fresnel diffraction that can be applied to the propagation of waves in the near field. It is used to calculate the diffraction pattern created by waves passing through an aperture or around an object, when viewed from relatively close to the object. In contrast the diffraction pattern in the far field region is given by the Fraunhofer diffraction equation. " - Diffracted field

WebShow (for normally incident plane waves) that if an aperture has a center of symmetry (i.e., if the aperture function is even), then the diffracted field in the Fraunhofer case also possesses a center of symmetry.

WebIn fact, diffracted energy is inherent to the propagation of energy fields, and the presence of obstructions in their path merely changes the field properties by excluding a portion of it. This produces various interference … WebDiffraction occurs when light propagates through an ultrasonic field. Theoretically, the distinction between different orders of diffracted light is obvious. However, instead of being ideal, the lasers we used during the experiment had a divergence angle, causing different orders of diffracted light to interfere with each other.
