Four-wave mixing — is an intermodulation phenomenon in optical systems, whereby interactions between 3 wavelengths produce a 4th wavelength in the signal. It is similar to the third order intercept point in electrical systems. Four wave mixing can be compared to… … Wikipedia
Photon mapping — In computer graphics, photon mapping is a two pass global illumination algorithm developed by Henrik Wann Jensen that solves the rendering equation. Rays from the light source and rays from the camera are traced independently until some… … Wikipedia
Delbruck scattering — Delbrück scattering, the deflection of high energy photons in the Coulomb field of nuclei as a consequence of vacuum polarization has been observed. However, the process of scattering of light by light, has not been observed.[1] In both cases, it … Wikipedia
Raman scattering — or the Raman effect (pronounced: IPA| [rə.mən] ) is the inelastic scattering of a photon. Discovered By Dr. C.V. Raman in liquids and by Grigory Landsberg and Leonid Mandelstam in crystals.When light is scattered from an atom or molecule, most… … Wikipedia
