WebNode Parameter Description Default Value Type Specifies Fresnel type Standard: More well known fresnel effect Schlick: Approximation for fresnel equation using reflectance at normal incidence Schlick IOR: Approximation for fresnel equation using index of refraction Standard Normal Vector Specifies in which coordinates space the normal vector is WebThe Fresnel number is a useful concept in physical optics. The Fresnel number establishes a coarse criterion to define the near and far field approximations. Essentially, if Fresnel number is small – less than roughly 1 – the beam is said to be in the far field. If Fresnel number is larger than 1, the beam is said to be near field.

Near-field diffraction [ edit] Main article: Fresnel diffraction
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…
