All three terms were coined by Augustin-Jean Fresnel, in a memoir read to the French Academy of Sciences on 9 December 1822. [1] [2] Fresnel had first described the case of circular polarization, without yet naming it, in 1821. [3] The phenomenon of polarization arises as a consequence of the fact that light behaves as a two-dimensional ...
Prism rotators use multiple internal reflections to produce beams with rotated polarization. Because they are based on total internal reflection, they are broadband—they work over a broad range of wavelengths. [1] Double Fresnel rhomb A double Fresnel rhomb rotates the linear polarization axis by 90° using four internal reflections. A ...
Similar calculations for the near field can be made by applying the Fresnel diffraction equation, which implies that as the plane of observation gets closer to the plane in which the slits are located, the diffraction patterns associated with each slit decrease in size, so that the area in which interference occurs is reduced, and may vanish ...
Fresnel zone antennas belong to the category of reflector and lens antennas.Unlike traditional reflector and lens antennas, however, the focusing effect in a Fresnel zone antenna is achieved by controlling the phase shifting property of the surface and allows for flat [1] [6] or arbitrary antenna shapes. [4]
Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically. It was first introduced by Hermann von Helmholtz in late 19th-century Germany as supportive evidence for his perceptual learning theory (Helmholtz, 1909/1962). [1]
Close-up of the surface of a lenticular print. Lenticular printing is a technology in which lenticular lenses (a technology also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as they are viewed from different angles.
In 3D computer graphics, Schlick’s approximation, named after Christophe Schlick, is a formula for approximating the contribution of the Fresnel factor in the specular reflection of light from a non-conducting interface (surface) between two media.
Propagation of a ray through a layer. The transfer-matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified medium; a stack of thin films.
