Fresnel (disambiguation)

Fresnel most commonly refers to physicist Augustin-Jean Fresnel (1788–1827).

Fresnel may also refer to:

• Fresnel equations, describe the proportion of light reflected or refracted at an interface
  • Derivation of the Fresnel equations from electromagnetic principles
• Fresnel lens, an especially thin lens used especially for concentrating light
  • Fresnel lantern, a theatre spotlight incorporating a Fresnel lens
  • Hyperradiant Fresnel lens, an obsolete Fresnel lens used in lighthouses
• Huygens–Fresnel principle, the discovery of light propagation as a wave
• Fresnel diffraction (or Fresnel pattern), describes interference of light in the near field due to an aperture or edge
  • Fresnel integral, functions which calculate Fresnel diffraction around an edge
• Fresnel zone plate, a simple diffractive optical element (DOE) which focuses light of one wavelength
  • Fresnel Imager, a proposed design for a space telescope that uses Fresnel zone plates
• Fresnel number, parameter that specifies when Fresnel or Fraunhofer diffraction applies
• Fresnel rhomb, a prism that changes linear to circularly polarized light
• Fresnel zone, region between a transmitting and receiving antenna where most of the radio wave propagates
• Fresnel diffraction mirror or ridged mirror, reflects an atomic beam at grazing incidence
• Fresnel (frequency), a formerly-used unit equal to one terahertz.
• Fresnel drag coefficient, a parameter used in early attempts to explain the constant speed of light
• Fulgence Fresnel (1795–1855), a French Orientalist and brother of Augustin-Jean Fresnel
• Rimae Fresnel, an escarpment on the moon
