The near-field imaging of sample objects on a micrometer scale was approached in the frame work of a masters’ thesis.
WebAbstract. The need for modification of the Huygens-Fresnel superposition principle arises even in the description of the free fields of massive particles and, more extensively, in nonlinear field ... Webcall (10.1) the Huygens-Fresnel2 diffraction formula, although Fresnel is credited with this integral formulation. The factor ¡i/‚ in front of the integral in (10.1) ensures the right phase and field strength (not to mention correct units). Justifica-tion for this factor is given in section10.3and in appendix10.A. To summarize,
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 t… WebIn 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.
