WebL' indice de réfraction (souvent noté n ; en anglais, index of refraction ou IOR) est une grandeur sans dimension caractéristique d'un milieu, décrivant le comportement de la lumière dans celui-ci ; il dépend de la longueur d'onde de mesure mais aussi des caractéristiques de l'environnement (notamment pression et température). Web2 jun. 2015 · The index of refraction, n, is a known value which can be obtained from the fiber optics manufacturer. While t , OTDR pulse width and its backscatter light travelling time , can be measured by OTDR automatically ie. the initial time laser pulse width launched into fiber optics and time taken by backscattered light returned back into OTDR.

Web5 apr. 2024 · The refraction algorithms in Eevee (which the glass shader uses either) lower resolution of everything behind refracted surface to speed up render and performance - this is what causes the bluriness. If you don't need a refraction distortion, the solution as it has been already mentioned is in using Principled BSDF. Web1 nov. 2024 · For real materials, the IOR is a function of the wavelength λ of light. This property is called dispersion. For example, the IOR of N-BK7 glass, a common glass for laboratory optics, varies between n = 1.53 at a λ = 400 nm, to n = 1.51 at λ = 800 nm. This may not seem a big difference, but it has significant impact on imaging optics.
