Fresnel in a sentence

Aether drag models seeAlso Fresnel's aether drag In 1818, Augustin Fresnel developed a modified explanation to account for the water telescope and for other aberration phenomena.

Although Fresnel, who had also the satisfaction of being the first to put it into operation, perfected the dioptric apparatus independently, Brewster was active earlier in the field than Fresnel, describing the dioptric apparatus in 1812.

Close-up view of a flat Fresnel lens A Fresnel lens has its optical surface broken up into narrow rings, allowing the lens to be much thinner and lighter than conventional lenses.

Determining Fresnel zone clearance Several examples of how the Fresnel zone can be disrupted.

French physicist and engineer Augustin-Jean Fresnel developed the multi-part Fresnel lens for use in lighthouses.

Speckles can be observed also close to the scattering object, in the near field (also called Fresnel region, that is, the region where Fresnel diffraction happens).

Stokes' aether drag However, the fact that light is polarized (discovered by Fresnel himself) led scientists such as Cauchy and Green to believe that the aether was a totally immobile elastic solid as opposed to Fresnel's fluid aether.

The cross sectional radius of each Fresnel zone is the longest at the midpoint of the RF LoS, For practical applications, it is often useful to know the maximum radius of the first Fresnel zone.

The Quest 3 uses fresnel lenses compared to the 3’s pancake lenses.

A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet.

A planet-sized mirror or fresnel lens would be need be located at several dozen astronomical units from the Sun to keep the lasers focused on the sail.

A wide range of concentrating technologies exists; the most developed are the parabolic trough, the concentrating linear fresnel reflector, the Stirling dish and the solar power tower.

A year later, Thomas Young demonstrated the wave nature of light—which received strong experimental support from the work of Augustin-Jean Fresnel —and the principle of interference.

Besides those optical experiments, also electrodynamic first-order experiments were conducted, which should have led to positive results according to Fresnel.

By the time of the fourth album he began involving elaborate stage props and acrobatics which had him suspended from gantries, distorting his face with Fresnel lenses and mirrors, and wearing unusual make-up.

By the year 1821, Fresnel was able to show via mathematical methods that polarisation could be explained by the wave theory of light and only if light was entirely transverse, with no longitudinal vibration whatsoever.

By this time flaws were known to both Fresnel's and Stokes' theories.

Consequently, there should be no reflective objects in the 1st Fresnel zone.

Design Gilliam used the same filmmaking style as he had in Brazil (1985), including the art direction and cinematography (specifically using fresnel lenses ).

Durable Fresnel lenses can be molded from plastic and are inexpensive.
